Relative Estimated Price KivanÇ version (Strategy) By Wicksell

Thanks to the great work of KIVANÇ in the Relative Estimated Price REP by KIVANÇ fr3762, it has adapted modifications in the Lookback bar length, transformed into strategy, where a line determines a relative average price of XBTUSD, BTCUSD, ETHUSD and BCH.

the line is a calculation, where it involves reading previous candles where it determines what the current price should be.

When the REP line is above the candle, open buy and close sell, when it is below, open sell and close buy.

When setting which currency, do not forget to change the settings where they are:
1 - XBTUSD
2 - BTCUSD
3 - ETHUSD
4 - BCHBTC

may also be modified:
the Lookback bar length, stop loss settings, test date.

The best results are in the 1H time, with the default settings, but try to modify the data and if you find better results, I would be grateful if you post here.
