This is a moving average channel-based scalping strategy that is optimized for very short time-frames.
In general, the optimal settings will be for the fast channel to be several periods shorter than the slow channel and the fast HMA (hull moving average) to be a few periods shorter than the fast channel.
This strategy can offer wild swings in profitability with relatively small parameter changes, so I HIGHLY recommend you cross-validate any set of parameters across multiple exchanges AND across multiple tickers.
