Exchange-specific Notes¶
This page combines common gotchas and informations which are exchange-specific and most likely don't apply to other exchanges.
Binance¶
Stoploss on Exchange
Binance supports stoploss_on_exchange and uses stop-loss-limit orders. It provides great advantages, so we recommend to benefit from it.
Binance Blacklist¶
For Binance, please add "BNB/<STAKE>" to your blacklist to avoid issues.
Accounts having BNB accounts use this to pay for fees - if your first trade happens to be on BNB, further trades will consume this position and make the initial BNB trade unsellable as the expected amount is not there anymore.
Binance sites¶
Binance has been split into 2, and users must use the correct ccxt exchange ID for their exchange, otherwise API keys are not recognized.
- binance.com - International users. Use exchange id:
binance. - binance.us - US based users. Use exchange id:
binanceus.
Kraken¶
Stoploss on Exchange
Kraken supports stoploss_on_exchange and can use both stop-loss-market and stop-loss-limit orders. It provides great advantages, so we recommend to benefit from it.
You can use either "limit" or "market" in the order_types.stoploss configuration setting to decide which type to use.
Historic Kraken data¶
The Kraken API does only provide 720 historic candles, which is sufficient for Freqtrade dry-run and live trade modes, but is a problem for backtesting.
To download data for the Kraken exchange, using --dl-trades is mandatory, otherwise the bot will download the same 720 candles over and over, and you'll not have enough backtest data.
Due to the heavy rate-limiting applied by Kraken, the following configuration section should be used to download data:
json
"ccxt_async_config": {
"enableRateLimit": true,
"rateLimit": 3100
},
Downloading data from kraken
Downloading kraken data will require significantly more memory (RAM) than any other exchange, as the trades-data needs to be converted into candles on your machine. It will also take a long time, as freqtrade will need to download every single trade that happened on the exchange for the pair / timerange combination, therefore please be patient.
rateLimit tuning
Please pay attention that rateLimit configuration entry holds delay in milliseconds between requests, NOT requests\sec rate. So, in order to mitigate Kraken API "Rate limit exceeded" exception, this configuration should be increased, NOT decreased.
Bittrex¶
Order types¶
Bittrex does not support market orders. If you have a message at the bot startup about this, you should change order type values set in your configuration and/or in the strategy from "market" to "limit". See some more details on this here in the FAQ.
Bittrex also does not support VolumePairlist due to limited / split API constellation at the moment.
Please use StaticPairlist. Other pairlists (other than VolumePairlist) should not be affected.
Restricted markets¶
Bittrex split its exchange into US and International versions. The International version has more pairs available, however the API always returns all pairs, so there is currently no automated way to detect if you're affected by the restriction.
If you have restricted pairs in your whitelist, you'll get a warning message in the log on Freqtrade startup for each restricted pair.
The warning message will look similar to the following:
output
[...] Message: bittrex {"success":false,"message":"RESTRICTED_MARKET","result":null,"explanation":null}"
If you're an "International" customer on the Bittrex exchange, then this warning will probably not impact you. If you're a US customer, the bot will fail to create orders for these pairs, and you should remove them from your whitelist.
You can get a list of restricted markets by using the following snippet:
``` python import ccxt ct = ccxt.bittrex() lm = ct.load_markets()
res = [p for p, x in lm.items() if 'US' in x['info']['prohibitedIn']] print(res) ```
FTX¶
Stoploss on Exchange
FTX supports stoploss_on_exchange and can use both stop-loss-market and stop-loss-limit orders. It provides great advantages, so we recommend to benefit from it.
You can use either "limit" or "market" in the order_types.stoploss configuration setting to decide which type of stoploss shall be used.
Using subaccounts¶
To use subaccounts with FTX, you need to edit the configuration and add the following:
json
"exchange": {
"ccxt_config": {
"headers": {
"FTX-SUBACCOUNT": "name"
}
},
}
Kucoin¶
Kucoin requries a passphrase for each api key, you will therefore need to add this key into the configuration so your exchange section looks as follows:
json
"exchange": {
"name": "kucoin",
"key": "your_exchange_key",
"secret": "your_exchange_secret",
"password": "your_exchange_api_key_password",
Kucoin Blacklists¶
For Kucoin, please add "KCS/<STAKE>" to your blacklist to avoid issues.
Accounts having KCS accounts use this to pay for fees - if your first trade happens to be on KCS, further trades will consume this position and make the initial KCS trade unsellable as the expected amount is not there anymore.
All exchanges¶
Should you experience constant errors with Nonce (like InvalidNonce), it is best to regenerate the API keys. Resetting Nonce is difficult and it's usually easier to regenerate the API keys.
Random notes for other exchanges¶
- The Ocean (exchange id:
theocean) exchange uses Web3 functionality and requiresweb3python package to be installed:
shell
$ pip3 install web3
Getting latest price / Incomplete candles¶
Most exchanges return current incomplete candle via their OHLCV/klines API interface. By default, Freqtrade assumes that incomplete candle is fetched from the exchange and removes the last candle assuming it's the incomplete candle.
Whether your exchange returns incomplete candles or not can be checked using the helper script from the Contributor documentation.
Due to the danger of repainting, Freqtrade does not allow you to use this incomplete candle.
However, if it is based on the need for the latest price for your strategy - then this requirement can be acquired using the data provider from within the strategy.
Advanced Freqtrade Exchange configuration¶
Advanced options can be configured using the _ft_has_params setting, which will override Defaults and exchange-specific behavior.
Available options are listed in the exchange-class as _ft_has_default.
For example, to test the order type FOK with Kraken, and modify candle limit to 200 (so you only get 200 candles per API call):
json
"exchange": {
"name": "kraken",
"_ft_has_params": {
"order_time_in_force": ["gtc", "fok"],
"ohlcv_candle_limit": 200
}
Warning
Please make sure to fully understand the impacts of these settings before modifying them.
