Beginner Tips & Tricks

#1 When you work with your strategy & hyperopt file you should use a real programmer software like Pycharm. If you by accident moved some code and freqtrade says error and you cant find the place where you moved something, or you cant find line 180 where you messed something up. Then a program like Pycharm shows you where line 180 is in your strategy file so you can fix the problem, or Pycharm shows you with some color marking that "here is a line of code that does not belong here" and you found your error in no time! This will save you many hours of problemsolving when working with the bot. Pycharm also got a usefull "Debug" feature that can tell you exactly what command on that line is making the error :)

Freqtrade common issues

The bot does not start

Running the bot with freqtrade trade --config config.json does show the output freqtrade: command not found.

This could have the following reasons:

The virtual environment is not active
- run source .env/bin/activate to activate the virtual environment
The installation did not work correctly.
- Please check the Installation documentation.

I have waited 5 minutes, why hasn't the bot made any trades yet?!

Depending on the buy strategy, the amount of whitelisted coins, the situation of the market etc, it can take up to hours to find good entry position for a trade. Be patient!
Or it may because of a configuration error? Best check the logs, it's usually telling you if the bot is simply not getting buy signals (only heartbeat messages), or if there is something wrong (errors / exceptions in the log).

I have made 12 trades already, why is my total profit negative?!

I understand your disappointment but unfortunately 12 trades is just not enough to say anything. If you run backtesting, you can see that our current algorithm does leave you on the plus side, but that is after thousands of trades and even there, you will be left with losses on specific coins that you have traded tens if not hundreds of times. We of course constantly aim to improve the bot but it will always be a gamble, which should leave you with modest wins on monthly basis but you can't say much from few trades.

I’d like to change the stake amount. Can I just stop the bot with /stop and then change the config.json and run it again?

Not quite. Trades are persisted to a database but the configuration is currently only read when the bot is killed and restarted. /stop more like pauses. You can stop your bot, adjust settings and start it again.

I want to improve the bot with a new strategy

That's great. We have a nice backtesting and hyperoptimization setup. See the tutorial here|Testing-new-strategies-with-Hyperopt.

Is there a setting to only SELL the coins being held and not perform anymore BUYS?

You can use the /forcesell all command from Telegram.

I want to run multiple bots on the same machine

Please look at the advanced setup documentation Page.

I'm getting "Missing data fillup" messages in the log

This message is just a warning that the latest candles had missing candles in them. Depending on the exchange, this can indicate that the pair didn't have a trade for the timeframe you are using - and the exchange does only return candles with volume. On low volume pairs, this is a rather common occurance.

If this happens for all pairs in the pairlist, this might indicate a recent exchange downtime. Please check your exchange's public channels for details.

Irrespectively of the reason, Freqtrade will fill up these candles with "empty" candles, where open, high, low and close are set to the previous candle close - and volume is empty. In a chart, this will look like a _ - and is aligned with how exchanges usually represent 0 volume candles.

I'm getting the "RESTRICTED_MARKET" message in the log

Currently known to happen for US Bittrex users.

Read the Bittrex section about restricted markets for more information.

I'm getting the "Exchange Bittrex does not support market orders." message and cannot run my strategy

As the message says, Bittrex does not support market orders and you have one of the order types set to "market". Probably your strategy was written with other exchanges in mind and sets "market" orders for "stoploss" orders, which is correct and preferable for most of the exchanges supporting market orders (but not for Bittrex).

To fix it for Bittrex, redefine order types in the strategy to use "limit" instead of "market":

    order_types = {
        ...
        'stoploss': 'limit',
        ...
    }

Same fix should be done in the configuration file, if order types are defined in your custom config rather than in the strategy.

How do I search the bot logs for something?

By default, the bot writes its log into stderr stream. This is implemented this way so that you can easily separate the bot's diagnostics messages from Backtesting, Edge and Hyperopt results, output from other various Freqtrade utility subcommands, as well as from the output of your custom print()'s you may have inserted into your strategy. So if you need to search the log messages with the grep utility, you need to redirect stderr to stdout and disregard stdout.

In unix shells, this normally can be done as simple as:

$ freqtrade --some-options 2>&1 >/dev/null | grep 'something'

(note, 2>&1 and >/dev/null should be written in this order)

Bash interpreter also supports so called process substitution syntax, you can grep the log for a string with it as:

$ freqtrade --some-options 2> >(grep 'something') >/dev/null

$ freqtrade --some-options 2> >(grep -v 'something' 1>&2)

You can also write the copy of Freqtrade log messages to a file with the --logfile option:

$ freqtrade --logfile /path/to/mylogfile.log --some-options

and then grep it as:

$ cat /path/to/mylogfile.log | grep 'something'

or even on the fly, as the bot works and the logfile grows:

$ tail -f /path/to/mylogfile.log | grep 'something'

from a separate terminal window.

On Windows, the --logfile option is also supported by Freqtrade and you can use the findstr command to search the log for the string of interest:

> type \path\to\mylogfile.log | findstr "something"

Hyperopt module

How many epoch do I need to get a good Hyperopt result?

Per default Hyperopt called without the -e/--epochs command line option will only run 100 epochs, means 100 evals of your triggers, guards, ... Too few to find a great result (unless if you are very lucky), so you probably have to run it for 10.000 or more. But it will take an eternity to compute.

Since hyperopt uses Bayesian search, running for too many epochs may not produce greater results.

It's therefore recommended to run between 500-1000 epochs over and over until you hit at least 10.000 epocs in total (or are satisfied with the result). You can best judge by looking at the results - if the bot keeps discovering better strategies, it's best to keep on going.

freqtrade hyperopt -e 1000

or if you want intermediate result to see

for i in {1..100}; do freqtrade hyperopt -e 1000; done

Why does it take a long time to run hyperopt?

Discovering a great strategy with Hyperopt takes time. Study www.freqtrade.io, the Freqtrade Documentation page, join the Freqtrade Slack community - or the Freqtrade discord community. While you patiently wait for the most advanced, free crypto bot in the world, to hand you a possible golden strategy specially designed just for you.
If you wonder why it can take from 20 minutes to days to do 1000 epocs here are some answers:

This answer was written during the release 0.15.1, when we had:

8 triggers
9 guards: let's say we evaluate even 10 values from each
1 stoploss calculation: let's say we want 10 values from that too to be evaluated

The following calculation is still very rough and not very precise but it will give the idea. With only these triggers and guards there is already 8*10^9*10 evaluations. A roughly total of 80 billion evals. Did you run 100 000 evals? Congrats, you've done roughly 1 / 100 000 th of the search space, assuming that the bot never tests the same parameters more than once.

The time it takes to run 1000 hyperopt epocs depends on things like: The available cpu, harddisk, ram, timeframe, timerange, indicator settings, indicator count, amount of coins that hyperopt test strategies on and the resulting trade count - which can be 650 trades in a year or 10.0000 trades depending if the strategy aims for big profits by trading rarely or for many low profit trades.

Example: 4% profit 650 times vs 0,3% profit a trade 10.000 times in a year. If we assume you set the --timerange to 365 days.

Example: freqtrade --config config.json --strategy SampleStrategy --hyperopt SampleHyperopt -e 1000 --timerange 20190601-20200601

Edge module

Edge implements interesting approach for controlling position size, is there any theory behind it?

The Edge module is mostly a result of brainstorming of @mishaker and @creslinux freqtrade team members.

You can find further info on expectancy, winrate, risk management and position size in the following sources:
