Coded for micro DAX €1 (simply multiply by 25 to run on standard DAX €25 or by 5 to run on mini DAX €5), 1-hour TF.

I used the Multiple Time Frame support to allow Breakeven/Trailing Stop to run on 1-minute bars (default TF).

Strategy from https://www.forexstrategiesresources.com/trend-following-forex-strategies/111-kama-strategy/.

Compared to the original version at the above link, I only optimized the SMA (called MVA in the above site) and set it to 22, instead of 7.

I also added SL & TP plus my own Breakeven/Trailing Stop code snippet.

Lines 10-11 allow to enable/disable Long/Short trading (both enabled by default).

Lines 21-25, along with lines 54-61 and lines 67 and 74, ban further trading before a whole 1-hour bar has elapsed, in case a trade exits within a few 1-minute bars. In such case the 1-hour signal is still set and valid, but it would most likely lead to a losing trade since the momentum is likely to have faded.
