I like the rules, but as there aren't too many true traders with long trackrecods in darwinex it would be difficult to backtest them. Hmm probably it is not the same a 20% DD in 6 months, than a 20% DD in 2 years. Although I'm not sure about what could be the right balance.
For instance, 31/7/2018 YZZ had 6m, 1y and 2y <0, just before it exploded upwards:
(To be fair and strictly speaking, it was 0% two years minus a week or so, but you get the idea)
What about something like a range for the longest period? I mean, if the trackrecord is long and nice, but the last 2y didn't do very well, but neither very bad, may be it is just waiting the right market conditions. Something like 2y <-5% or <-10%?:
Return 2y <-10 AND Return 1y <0 AND Return 6m <0
