Here is a backtest result from the beginning of the year on BTC. The white line is the Buy & Hold return. Comission is set to 0.05% and there is no repainting : the price variable I'm using is heikenashi(tickerid).
The indicator is built upon RSI, EMAs and some other personnal tricks so predict trends. I coded a stop loss and take profit system : the script will simply buy and sell upon conditions.
As usual I am selling access to the script, If some are interested I will publish an alert setup version. I am also open to development or reverse engineering commissions.
