# Backtesting
|
||
|
||
This page explains how to validate your strategy performance by using Backtesting.
|
||
|
||
Backtesting requires historic data to be available.
|
||
To learn how to get data for the pairs and exchange you're interested in, head over to the [Data Downloading](data-download.md) section of the documentation.
|
||
|

|
||
backtest. Please note that ticker-interval needs to be
|
||
set either in config or via command line. When using
|
||
this together with `--export trades`, the strategy-
|
||

|
||
data.json` becomes `backtest-data-
|
||

|
||
--export {none,trades}
|
||
Export backtest results (default: trades).

|
||
`--export-filename=user_data/backtest_results/backtest
|
||
_today.json`
|
||
|
||
Common arguments:
|
||
-v, --verbose Verbose mode (-vv for more, -vvv to get all messages).
|
||
--logfile FILE Log to the file specified. Special values are:
|
||

||
Strategy arguments:
|
||
-s NAME, --strategy NAME
|
||
Specify strategy class name which will be used by the
|
||
bot.
|
||
--strategy-path PATH Specify additional strategy lookup path.
|
||
|
||
```
|
||
|
||
## Test your strategy with Backtesting
|
||
|
||
Now you have good Buy and Sell strategies and some historic data, you want to test it against
|
||
real data. This is what we call [backtesting](https://en.wikipedia.org/wiki/Backtesting).
|
||
|
||
Backtesting will use the crypto-currencies (pairs) from your config file and load historical candle (OHLCV) data from `user_data/data/<exchange>` by default.
|
||
If no data is available for the exchange / pair / timeframe combination, backtesting will ask you to download them first using `freqtrade download-data`.
|
||
For details on downloading, please refer to the [Data Downloading](data-download.md) section in the documentation.
|
||
|
||
The result of backtesting will confirm if your bot has better odds of making a profit than a loss.
|
||
|
||
All profit calculations include fees, and freqtrade will use the exchange's default fees for the calculation.
|
||
|
||
!!! Warning "Using dynamic pairlists for backtesting"
|
||
Using dynamic pairlists is possible, however it relies on the current market conditions - which will not reflect the historic status of the pairlist.
|
||
Also, when using pairlists other than StaticPairlist, reproducibility of backtesting-results cannot be guaranteed.
|
||
Please read the [pairlists documentation](plugins.md#pairlists) for more information.
|
||
|
||
To achieve reproducible results, best generate a pairlist via the [`test-pairlist`](utils.md#test-pairlist) command and use that as static pairlist.
|
||
|
||
!!! Note
|
||
By default, Freqtrade will export backtesting results to `user_data/backtest_results`.
|
||
The exported trades can be used for [further analysis](#further-backtest-result-analysis) or can be used by the [plotting sub-command](plotting.md#plot-price-and-indicators) (`freqtrade plot-dataframe`) in the scripts directory.
|
||
|
||
|
||
### Starting balance
|
||
|
||
Backtesting will require a starting balance, which can be provided as `--dry-run-wallet <balance>` or `--starting-balance <balance>` command line argument, or via `dry_run_wallet` configuration setting.
|
||
This amount must be higher than `stake_amount`, otherwise the bot will not be able to simulate any trade.
|
||
|
||
### Dynamic stake amount
|
||
|
||
Backtesting supports [dynamic stake amount](configuration.md#dynamic-stake-amount) by configuring `stake_amount` as `"unlimited"`, which will split the starting balance into `max_open_trades` pieces.
|
||
Profits from early trades will result in subsequent higher stake amounts, resulting in compounding of profits over the backtesting period.
|
||
|
||
### Example backtesting commands
|
||
|
||
With 5 min candle (OHLCV) data (per default)
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy AwesomeStrategy
|
||
```
|
||
|
||
Where `--strategy AwesomeStrategy` / `-s AwesomeStrategy` refers to the class name of the strategy, which is within a python file in the `user_data/strategies` directory.
|
||
|
||
---
|
||
|
||
With 1 min candle (OHLCV) data
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy AwesomeStrategy --timeframe 1m
|
||
```
|
||
|
||
---
|
||
|
||
Providing a custom starting balance of 1000 (in stake currency)
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy AwesomeStrategy --dry-run-wallet 1000
|
||
```
|
||
|
||
---
|
||
|
||
Using a different on-disk historical candle (OHLCV) data source
|
||
|
||
Assume you downloaded the history data from the Bittrex exchange and kept it in the `user_data/data/bittrex-20180101` directory.
|
||
You can then use this data for backtesting as follows:
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy AwesomeStrategy --datadir user_data/data/bittrex-20180101
|
||
```
|
||
|
||
---
|
||
|
||
Comparing multiple Strategies
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy-list SampleStrategy1 AwesomeStrategy --timeframe 5m
|
||
```
|
||
|
||
Where `SampleStrategy1` and `AwesomeStrategy` refer to class names of strategies.
|
||
|
||
---
|
||
|
||
Prevent exporting trades to file
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy backtesting --export none --config config.json
|
||
```
|
||
|
||
Only use this if you're sure you'll not want to plot or analyze your results further.
|
||
|
||
---
|
||
|
||
Exporting trades to file specifying a custom filename
|
||
|
||
```bash
|
||
freqtrade backtesting --strategy backtesting --export trades --export-filename=backtest_samplestrategy.json
|
||
```
|
||
|
||
Please also read about the [strategy startup period](strategy-customization.md#strategy-startup-period).
|
||
|
||
---
|
||
|
||
Supplying custom fee value
|
||
|
||
Sometimes your account has certain fee rebates (fee reductions starting with a certain account size or monthly volume), which are not visible to ccxt.
|
||
To account for this in backtesting, you can use the `--fee` command line option to supply this value to backtesting.
|
||
This fee must be a ratio, and will be applied twice (once for trade entry, and once for trade exit).
|
||
|
||
For example, if the buying and selling commission fee is 0.1% (i.e., 0.001 written as ratio), then you would run backtesting as the following:
|
||
|
||
```bash
|
||
freqtrade backtesting --fee 0.001
|
||
```
|
||
|
||
!!! Note
|
||
Only supply this option (or the corresponding configuration parameter) if you want to experiment with different fee values. By default, Backtesting fetches the default fee from the exchange pair/market info.
|
||
|
||
---
|
||
|
||
Running backtest with smaller test-set by using timerange
|
||
|
||
Use the `--timerange` argument to change how much of the test-set you want to use.
|
||
|
||
For example, running backtesting with the `--timerange=20190501-` option will use all available data starting with May 1st, 2019 from your input data.
|
||
|
||
```bash
|
||
freqtrade backtesting --timerange=20190501-
|
||
```
|
||
|
||
You can also specify particular date ranges.
|
||
|
||
The full timerange specification:
|
||
|
||
- Use data until 2018/01/31: `--timerange=-20180131`
|
||
- Use data since 2018/01/31: `--timerange=20180131-`
|
||
- Use data since 2018/01/31 till 2018/03/01 : `--timerange=20180131-20180301`
|
||
- Use data between POSIX / epoch timestamps 1527595200 1527618600: `--timerange=1527595200-1527618600`
|
||
|
||
## Understand the backtesting result
|
||
|
||
The most important in the backtesting is to understand the result.
|
||
|
||
A backtesting result will look like that:
|
||
|
||
```

===============================================

|
||
|
||
### Backtesting report table
|
||
|
||
The 1st table contains all trades the bot made, including "left open trades".
|
||
|
||
The last line will give you the overall performance of your strategy,
|
||
here:
|
||
|
||
```
|
||
| TOTAL | 429 | 0.36 | 152.41 | 0.00762792 | 76.20 | 4:12:00 | 186 0 243 43.4 |
|
||
```
|
||
|
||
The bot has made `429` trades for an average duration of `4:12:00`, with a performance of `76.20%` (profit), that means it has
|
||
earned a total of `0.00762792 BTC` starting with a capital of 0.01 BTC.
|
||
|
||
The column `Avg Profit %` shows the average profit for all trades made while the column `Cum Profit %` sums up all the profits/losses.
|
||
The column `Tot Profit %` shows instead the total profit % in relation to the starting balance.
|
||
In the above results, we have a starting balance of 0.01 BTC and an absolute profit of 0.00762792 BTC - so the `Tot Profit %` will be `(0.00762792 / 0.01) * 100 ~= 76.2%`.
|
||
|
||
Your strategy performance is influenced by your buy strategy, your sell strategy, and also by the `minimal_roi` and `stop_loss` you have set.
|
||
|
||
For example, if your `minimal_roi` is only `"0": 0.01` you cannot expect the bot to make more profit than 1% (because it will sell every time a trade reaches 1%).
|
||
|
||
```json
|
||
"minimal_roi": {
|
||
"0": 0.01
|
||
},
|
||
```
|
||
|
||
On the other hand, if you set a too high `minimal_roi` like `"0": 0.55`
|
||
(55%), there is almost no chance that the bot will ever reach this profit.
|
||
Hence, keep in mind that your performance is an integral mix of all different elements of the strategy, your configuration, and the crypto-currency pairs you have set up.
|
||
|
||
### Sell reasons table
|
||
|
||
The 2nd table contains a recap of sell reasons.
|
||
This table can tell you which area needs some additional work (e.g. all or many of the `sell_signal` trades are losses, so you should work on improving the sell signal, or consider disabling it).
|
||
|
||
### Left open trades table
|
||
|
||
The 3rd table contains all trades the bot had to `forcesell` at the end of the backtesting period to present you the full picture.
|
||
This is necessary to simulate realistic behavior, since the backtest period has to end at some point, while realistically, you could leave the bot running forever.
|
||
These trades are also included in the first table, but are also shown separately in this table for clarity.
|
||
|
||
### Summary metrics
|
||
|
||
The last element of the backtest report is the summary metrics table.
|
||
It contains some useful key metrics about performance of your strategy on backtesting data.
|
||
|
||

```
|
||
|
||
- `Backtesting from` / `Backtesting to`: Backtesting range (usually defined with the `--timerange` option).
|
||
- `Max open trades`: Setting of `max_open_trades` (or `--max-open-trades`) - or number of pairs in the pairlist (whatever is lower).
|
||
- `Total/Daily Avg Trades`: Identical to the total trades of the backtest output table / Total trades divided by the backtesting duration in days (this will give you information about how many trades to expect from the strategy).
|
||
- `Starting balance`: Start balance - as given by dry-run-wallet (config or command line).
|
||
- `Final balance`: Final balance - starting balance + absolute profit.
|
||
- `Absolute profit`: Profit made in stake currency.
|
||
- `Total profit %`: Total profit. Aligned to the `TOTAL` row's `Tot Profit %` from the first table. Calculated as `(End capital − Starting capital) / Starting capital`.
|
||
- `Avg. stake amount`: Average stake amount, either `stake_amount` or the average when using dynamic stake amount.
|
||
- `Total trade volume`: Volume generated on the exchange to reach the above profit.
|
||
- `Best Pair` / `Worst Pair`: Best and worst performing pair, and it's corresponding `Cum Profit %`.
|
||
- `Best Trade` / `Worst Trade`: Biggest single winning trade and biggest single losing trade.
|
||
- `Best day` / `Worst day`: Best and worst day based on daily profit.
|
||
- `Days win/draw/lose`: Winning / Losing days (draws are usually days without closed trade).
|
||
- `Avg. Duration Winners` / `Avg. Duration Loser`: Average durations for winning and losing trades.
|
||
- `Rejected Buy signals`: Buy signals that could not be acted upon due to max_open_trades being reached.
|
||
- `Min balance` / `Max balance`: Lowest and Highest Wallet balance during the backtest period.
|
||
- `Drawdown`: Maximum drawdown experienced. For example, the value of 50% means that from highest to subsequent lowest point, a 50% drop was experienced).
|
||
- `Drawdown high` / `Drawdown low`: Profit at the beginning and end of the largest drawdown period. A negative low value means initial capital lost.
|
||
- `Drawdown Start` / `Drawdown End`: Start and end datetime for this largest drawdown (can also be visualized via the `plot-dataframe` sub-command).
|
||
- `Market change`: Change of the market during the backtest period. Calculated as average of all pairs changes from the first to the last candle using the "close" column.
|
||
|
||
### Further backtest-result analysis
|
||
|
||
To further analyze your backtest results, you can [export the trades](#exporting-trades-to-file).
|
||
You can then load the trades to perform further analysis as shown in our [data analysis](data-analysis.md#backtesting) backtesting section.
|
||
|
||
## Assumptions made by backtesting
|
||
|
||
Since backtesting lacks some detailed information about what happens within a candle, it needs to take a few assumptions:
|
||
|
||
- Buys happen at open-price
|
||
- All orders are filled at the requested price (no slippage, no unfilled orders)
|
||
- Sell-signal sells happen at open-price of the consecutive candle
|
||
- Sell-signal is favored over Stoploss, because sell-signals are assumed to trigger on candle's open
|
||
- ROI
|
||
- sells are compared to high - but the ROI value is used (e.g. ROI = 2%, high=5% - so the sell will be at 2%)
|
||
- sells are never "below the candle", so a ROI of 2% may result in a sell at 2.4% if low was at 2.4% profit
|
||
- Forcesells caused by `<N>=-1` ROI entries use low as sell value, unless N falls on the candle open (e.g. `120: -1` for 1h candles)
|
||
- Stoploss sells happen exactly at stoploss price, even if low was lower, but the loss will be `2 * fees` higher than the stoploss price
|
||
- Stoploss is evaluated before ROI within one candle. So you can often see more trades with the `stoploss` sell reason comparing to the results obtained with the same strategy in the Dry Run/Live Trade modes
|
||
- Low happens before high for stoploss, protecting capital first
|
||
- Trailing stoploss
|
||
- Trailing Stoploss is only adjusted if it's below the candle's low (otherwise it would be triggered)
|
||
- High happens first - adjusting stoploss
|
||
- Low uses the adjusted stoploss (so sells with large high-low difference are backtested correctly)
|
||
- ROI applies before trailing-stop, ensuring profits are "top-capped" at ROI if both ROI and trailing stop applies
|
||
- Sell-reason does not explain if a trade was positive or negative, just what triggered the sell (this can look odd if negative ROI values are used)
|
||
- Evaluation sequence (if multiple signals happen on the same candle)
|
||
- ROI (if not stoploss)
|
||
- Sell-signal
|
||
- Stoploss
|
||
|
||
Taking these assumptions, backtesting tries to mirror real trading as closely as possible. However, backtesting will **never** replace running a strategy in dry-run mode.
|
||
Also, keep in mind that past results don't guarantee future success.
|
||
|
||
In addition to the above assumptions, strategy authors should carefully read the [Common Mistakes](strategy-customization.md#common-mistakes-when-developing-strategies) section, to avoid using data in backtesting which is not available in real market conditions.
|
||
|
||
### Improved backtest accuracy
|
||
|
||
One big limitation of backtesting is it's inability to know how prices moved intra-candle (was high before close, or viceversa?).
|
||
So assuming you run backtesting with a 1h timeframe, there will be 4 prices for that candle (Open, High, Low, Close).
|
||
|
||
While backtesting does take some assumptions (read above) about this - this can never be perfect, and will always be biased in one way or the other.
|
||
To mitigate this, freqtrade can use a lower (faster) timeframe to simulate intra-candle movements.
|
||
|
||
To utilize this, you can append `--timeframe-detail 5m` to your regular backtesting command.
|
||
|
||
``` bash
|
||
freqtrade backtesting --strategy AwesomeStrategy --timeframe 1h --timeframe-detail 5m
|
||
```
|
||
|
||
This will load 1h data as well as 5m data for the timeframe. The strategy will be analyzed with the 1h timeframe - and for every "open trade candle" (candles where a trade is open) the 5m data will be used to simulate intra-candle movements.
|
||
All callback functions (`custom_sell()`, `custom_stoploss()`, ... ) will be running for each 5m candle once the trade is opened (so 12 times in the above example of 1h timeframe, and 5m detailed timeframe).
|
||
|
||
`--timeframe-detail` must be smaller than the original timeframe, otherwise backtesting will fail to start.
|
||
|
||
Obviously this will require more memory (5m data is bigger than 1h data), and will also impact runtime (depending on the amount of trades and trade durations).
|
||
Also, data must be available / downloaded already.
|
||
|
||
!!! Tip
|
||
You can use this function as the last part of strategy development, to ensure your strategy is not exploiting one of the [backtesting assumptions](#assumptions-made-by-backtesting). Strategies that perform similarly well with this mode have a good chance to perform well in dry/live modes too (although only forward-testing (dry-mode) can really confirm a strategy).
|
||
|
||
## Backtesting multiple strategies
|
||
|
||
To compare multiple strategies, a list of Strategies can be provided to backtesting.
|
||
|
||
This is limited to 1 timeframe value per run. However, data is only loaded once from disk so if you have multiple
|
||
strategies you'd like to compare, this will give a nice runtime boost.
|
||
|
||
All listed Strategies need to be in the same directory.
|
||
|
||
``` bash
|
||
freqtrade backtesting --timerange 20180401-20180410 --timeframe 5m --strategy-list Strategy001 Strategy002 --export trades
|
||
```
|
||
|
||
This will save the results to `user_data/backtest_results/backtest-result-<strategy>.json`, injecting the strategy-name into the target filename.
|
||
There will be an additional table comparing win/losses of the different strategies (identical to the "Total" row in the first table).
|
||
Detailed output for all strategies one after the other will be available, so make sure to scroll up to see the details per strategy.
