Rokas Kupstys 0e4466ca1e Implement strategy-controlled stake sizes. Expose self.wallet to a strategy. 2021-07-11 12:38:58 +03:00
Rokas Kupstys 3686efa08a Add range property to CategoricalParameter and DecimalParameter, add their tests.

Rokas Kupstys 29fed37df3 Fix exception when few pairs with no data do not result in aborting backtest. 
Exception is triggered by backtesting 20210301-20210501 range with BAKE/USDT pair (binance). Pair data starts on 2021-04-30 12:00:00 and after adjusting for startup candles pair dataframe is empty.

Solution: Since there are other pairs with enough data - skip pairs with no data and issue a warning.

Exception:

Rokas Kupstys ad4c51b3c5 * Added "Dataframe access" section showcasing how to obtain dataframe and use it to get last-available and trade-open candles. 
* Fix custom_sell() example to use rsi from last-available instead of trade-open candle, add a pointer to "Dataframe access" section for more info.
* Simplify "Custom stoploss using an indicator from dataframe example" greatly, add a pointer to "Dataframe access" section for more info.

Rokas Kupstys 09efa7b06b Add --new-pairs-days parameter for download-data command. 
This parameter allows us to customize a number of days we would like to download for new pairs only. This allows us to achieve efficient data update, downloading all data for new pairs and only missing data for existing pairs. To do that use `freqtrade download-data --new-pairs-days=3650` (not specifying `--days` or `--timerange` causes freqtrade to download only missing data for existing pairs).
