This is the strategy with backtest date range and trailing-stop / stop-loss for vitelot's Smeared VCI indicator:
This is a momentum, trend, as well as a divergence indicator. It is similar to CCI, though it is based on a slow and fast EMA in connection to ATR, which allows to interprete it easily. Both EMAs and ATR have customisable period. Further explanation and basic usage can be found in the comment section inside the script.
