I want to execute a strategy only if daily delta of BTC is positive and the market is in a bull trend.

: Strategy settings

You can set these conditions on the Filters tab of the strategy settings, using the following parameters:
Delta_BTC_24_Min=0.1 (Minimal change of BTC exchange rate in 24 hours (in %), below which the bot will not consider a coin)
Delta_BTC_24_Max=10 (Maximum change of BTC exchange rate in 24 hours (in %), above which the bot will not consider a coin)
That is, if BTC delta for 24 hours will lie in range from +0.1% to +10%, it will influence all coins and common market will grow that corresponds to bullish trend”.
