Coin not on binance per 1-1

[rayures]

When optimizing from 1-1 till 31-7 the resulting config file states start 1-1-2021 and end 31-7-2021. The script checks these values before uploading. When a coin is not on binance per 1-1 the backtest runs the days it was on binance. ie. per 1-5-2021. The resulting backtest results then states ie 91 days and probably with a higher adg, giving a false impression of a very good config file. The results.json still states 1-1 till 31-7, this is where the script checks.

make the script also check the backtest results days to match te timespan from 1-1 till 31-7 = 211 days.

This is also for the users that optimize a coin and do not know that a coin was not on binance since 1-1.

note: i also see values of 210.999 days in the backtest results. the script should handle this properly.
