# Analyzing bot data

After performing backtests, or after running the bot for some time, it will be interesting to analyze the results your bot generated.
|
You can analyze the results of backtests and trading history easily using Jupyter notebooks. A sample notebook is located at `user_data/notebooks/analysis_example.ipynb`. For usage instructions, see [jupyter.org](https://jupyter.org/documentation).
|
||||||
|
|
||||||
A good way for this is using Jupyter (notebook or lab) - which provides an interactive environment to analyze the data.
|
*Pro tip - Don't forget to start a jupyter notbook server from within your conda or venv environment or use [nb_conda_kernels](https://github.com/Anaconda-Platform/nb_conda_kernels)*
|
||||||
|
|
||||||
The following helpers will help you loading the data into Pandas DataFrames, and may also give you some starting points in analyzing the results.

### Load backtest results into a pandas dataframe
|
||||||
|
|
||||||
Debugging a strategy (are there no buy signals, ...) can be very time-consuming.
|
|
||||||
FreqTrade tries to help you by exposing a few helper-functions, which can be very handy.
|
|
||||||
|
|
||||||
It's recommended using Juptyer Notebooks for analysis, since it offers a dynamic way to rerun certain parts of the code.
|
|
||||||
|
|
||||||
The following is a full code-snippet, which will be explained by both comments, and step by step below.
|
|
||||||
|
|
||||||
```python
|
```python
|
||||||
# Some necessary imports
|
|
||||||
from pathlib import Path
|
|
||||||
|
|
||||||
from freqtrade.data.history import load_pair_history
|
|
||||||
from freqtrade.resolvers import StrategyResolver
|
|
||||||
# Define some constants
|
|
||||||
ticker_interval = "5m"
|
|
||||||
|
|
||||||
# Name of the strategy class
|
|
||||||
strategyname = 'Awesomestrategy'
|
|
||||||
# Location of the strategy
|
|
||||||
strategy_location = '../xmatt/strategies'
|
|
||||||
# Location of the data
|
|
||||||
data_location = '../freqtrade/user_data/data/binance/'
|
|
||||||
# Only use one pair here
|
|
||||||
pair = "XRP_ETH"
|
|
||||||
|
|
||||||
### End constants
|
|
||||||
|
|
||||||
# Load data
|
|
||||||
bt_data = load_pair_history(datadir=Path(data_location),
|
|
||||||
ticker_interval = ticker_interval,
|
|
||||||
pair=pair)
|
|
||||||
print(len(bt_data))
|
|
||||||
|
|
||||||
### Start strategy reload
|
|
||||||
# Load strategy - best done in a new cell
|
|
||||||
# Rerun each time the strategy-file is changed.
|
|
||||||
strategy = StrategyResolver({'strategy': strategyname,
|
|
||||||
'user_data_dir': Path.cwd(),
|
|
||||||
'strategy_path': location}).strategy
|
|
||||||
|
|
||||||
# Run strategy (just like in backtesting)
|
|
||||||
df = strategy.analyze_ticker(bt_data, {'pair': pair})
|
|
||||||
print(f"Generated {df['buy'].sum()} buy signals")
|
|
||||||
|
|
||||||
# Reindex data to be "nicer" and show data
|
|
||||||
data = df.set_index('date', drop=True)
|
|
||||||
data.tail()
|
|
||||||
|
|
||||||
```
|
|
||||||
|
|
||||||
### Explanation
|
|
||||||
|
|
||||||
#### Imports and constant definition
|
|
||||||
|
|
||||||
``` python
|
|
||||||
# Some necessary imports
|
|
||||||
from pathlib import Path
|
|
||||||
|
|
||||||
from freqtrade.data.history import load_pair_history
|
|
||||||
from freqtrade.resolvers import StrategyResolver
|
|
||||||
# Define some constants
|
|
||||||
ticker_interval = "5m"
|
|
||||||
|
|
||||||
# Name of the strategy class
|
|
||||||
strategyname = 'Awesomestrategy'
|
|
||||||
# Location of the strategy
|
|
||||||
strategy_location = 'user_data/strategies'
|
|
||||||
# Location of the data
|
|
||||||
data_location = 'user_data/data/binance'
|
|
||||||
# Only use one pair here
|
|
||||||
pair = "XRP_ETH"
|
|
||||||
```
|
|
||||||
|
|
||||||
This first section imports necessary modules, and defines some constants you'll probably need to adjust for your case.
|
|
||||||
|
|
||||||
#### Load candles
|
|
||||||
|
|
||||||
``` python
|
|
||||||
# Load data
|
|
||||||
bt_data = load_pair_history(datadir=Path(data_location),
|
|
||||||
ticker_interval = ticker_interval,
|
|
||||||
pair=pair)
|
|
||||||
print(len(bt_data))
|
|
||||||
```
|
|
||||||
|
|
||||||
This second section loads the historic data and prints the amount of candles in the DataFrame.
|
|
||||||
You can also inspect this dataframe by using `bt_data.head()` or `bt_data.tail()`.
|
|
||||||
|
|
||||||
#### Run strategy and analyze results
|
|
||||||
|
|
||||||
Now, it's time to load and run your strategy.
|
|
||||||
For this, I recommend using a new cell in your notebook, since you'll want to repeat this until you're satisfied with your strategy.
|
|
||||||
|
|
||||||
``` python
|
|
||||||
# Load strategy - best done in a new cell
|
|
||||||
# Needs to be ran each time the strategy-file is changed.
|
|
||||||
strategy = StrategyResolver({'strategy': strategyname,
|
|
||||||
'user_data_dir': Path.cwd(),
|
|
||||||
'strategy_path': location}).strategy
|
|
||||||
|
|
||||||
# Run strategy (just like in backtesting)
|
|
||||||
df = strategy.analyze_ticker(bt_data, {'pair': pair})
|
|
||||||
print(f"Generated {df['buy'].sum()} buy signals")
|
|
||||||
|
|
||||||
# Reindex data to be "nicer" and show data
|
|
||||||
data = df.set_index('date', drop=True)
|
|
||||||
data.tail()
|
|
||||||
```
|
|
||||||
|
|
||||||
The code snippet loads and analyzes the strategy, calculates and prints the number of buy signals.
|
|
||||||
|
|
||||||
The last 2 lines serve to analyze the dataframe in detail.
|
|
||||||
This can be important if your strategy did not generate any buy signals.
|
|
||||||
Note that using `data.head()` would also work, however this is misleading since most indicators have some "startup" time at the start of a backtested dataframe.
|
|
||||||
|
|
||||||
There can be many things wrong, some signs to look for are:
|
|
||||||
|
|
||||||
* Columns with NaN values at the end of the dataframe
|
|
||||||
* Columns used in `crossed*()` functions with completely different units
|
|
||||||
|
|
||||||
## Backtesting
|
|
||||||
|
|
||||||
To analyze your backtest results, you can [export the trades](#exporting-trades-to-file).
|
|
||||||
You can then load the trades to perform further analysis.
|
|
||||||
|
|
||||||
Freqtrade provides the `load_backtest_data()` helper function to easily load the backtest results, which takes the path to the the backtest-results file as parameter.
|
|
||||||
|
|
||||||
``` python
|
|
||||||
from freqtrade.data.btanalysis import load_backtest_data
|
from freqtrade.data.btanalysis import load_backtest_data
|
||||||
df = load_backtest_data("user_data/backtest-result.json")
|
# Load backtest results
|
||||||
|
df = load_backtest_data("user_data/backtest_data/backtest-result.json")
|
||||||
|
|
||||||
# Show value-counts per pair
|
# Show value-counts per pair
|
||||||
df.groupby("pair")["sell_reason"].value_counts()
|
df.groupby("pair")["sell_reason"].value_counts()
|
||||||
|
|
||||||
```
|
```
|
||||||
|
|
||||||
This will allow you to drill deeper into your backtest results, and perform analysis which otherwise would make the regular backtest-output very difficult to digest due to information overload.

### Load live trading results into a pandas dataframe
|
||||||
|
|
||||||
## Live data
|
|
||||||
|
|
||||||
To analyze the trades your bot generated, you can load them to a DataFrame as follows:
|
|
||||||
|
|
||||||
``` python
|
``` python
|
||||||
from freqtrade.data.btanalysis import load_trades_from_db
|
from freqtrade.data.btanalysis import load_trades_from_db
|
||||||
|
|
||||||
|
# Fetch trades from database
|
||||||
df = load_trades_from_db("sqlite:///tradesv3.sqlite")
|
df = load_trades_from_db("sqlite:///tradesv3.sqlite")
|
||||||
|
|
||||||
|
# Display results
|
||||||
df.groupby("pair")["sell_reason"].value_counts()
|
df.groupby("pair")["sell_reason"].value_counts()
|
||||||
|
```
|
||||||
|
|
||||||
|
## Strategy debugging example
|
||||||
|
|
||||||
|
Debugging a strategy can be time-consuming. FreqTrade offers helper functions to visualize raw data.
|
||||||
|
|
||||||
|
### Import requirements and define variables used in analyses
|
||||||
|
|
||||||
|
```python
|
||||||
|
# Imports
|
||||||
|
from pathlib import Path
|
||||||
|
import os
|
||||||
|
from freqtrade.data.history import load_pair_history
|
||||||
|
from freqtrade.resolvers import StrategyResolver
|
||||||
|
|
||||||
|
# You can override strategy settings as demonstrated below.
|
||||||
|
# Customize these according to your needs.
|
||||||
|
|
||||||
|
# Define some constants
|
||||||
|
ticker_interval = "5m"
|
||||||
|
# Name of the strategy class
|
||||||
|
strategy_name = 'AwesomeStrategy'
|
||||||
|
# Path to user data
|
||||||
|
user_data_dir = 'user_data'
|
||||||
|
# Location of the strategy
|
||||||
|
strategy_location = Path(user_data_dir, 'strategies')
|
||||||
|
# Location of the data
|
||||||
|
data_location = Path(user_data_dir, 'data', 'binance')
|
||||||
|
# Pair to analyze
|
||||||
|
# Only use one pair here
|
||||||
|
pair = "BTC_USDT"
|
||||||
|
```
|
||||||
|
|
||||||
|
### Load exchange data
|
||||||
|
|
||||||
|
```python
|
||||||
|
# Load data using values set above
|
||||||
|
bt_data = load_pair_history(datadir=Path(data_location),
|
||||||
|
ticker_interval=ticker_interval,
|
||||||
|
pair=pair)
|
||||||
|
|
||||||
|
# Confirm success
|
||||||
|
print(f"Loaded {len(bt_data)} rows of data for {pair} from {data_location}")
|
||||||
|
```
|
||||||
|
|
||||||
|
### Load and run strategy
|
||||||
|
|
||||||
|
* Rerun each time the strategy file is changed
|
||||||
|
|
||||||
|
```python
|
||||||
|
# Load strategy using values set above
|
||||||
|
strategy = StrategyResolver({'strategy': strategy_name,
|
||||||
|
'user_data_dir': user_data_dir,
|
||||||
|
'strategy_path': strategy_location}).strategy
|
||||||
|
|
||||||
|
# Generate buy/sell signals using strategy
|
||||||
|
df = strategy.analyze_ticker(bt_data, {'pair': pair})
|
||||||
|
```
|
||||||
|
|
||||||
|
### Display the trade details
|
||||||
|
|
||||||
|
* Note that using `data.head()` would also work, however most indicators have some "startup" data at the top of the dataframe.
|
||||||
|
|
||||||
|
#### Some possible problems
|
||||||
|
|
||||||
|
* Columns with NaN values at the end of the dataframe
|
||||||
|
* Columns used in `crossed*()` functions with completely different units
|
||||||
|
|
||||||
|
#### Comparison with full backtest
|
||||||
|
|
||||||
|
having 200 buy signals as output for one pair from `analyze_ticker()` does not necessarily mean that 200 trades will be made during backtesting.
|
||||||
|
|
||||||
|
Assuming you use only one condition such as, `df['rsi'] < 30` as buy condition, this will generate multiple "buy" signals for each pair in sequence (until rsi returns > 29).
|
||||||
|
The bot will only buy on the first of these signals (and also only if a trade-slot ("max_open_trades") is still available), or on one of the middle signals, as soon as a "slot" becomes available.
|
||||||
|
|
||||||
|
```python
|
||||||
|
# Report results
|
||||||
|
print(f"Generated {df['buy'].sum()} buy signals")
|
||||||
|
data = df.set_index('date', drop=True)
|
||||||
|
data.tail()
|
||||||
```
|
```
|
||||||

|
||||||
