Market selection is also the default excuse for many system sellers out there on why their strategy won't end up profitable for you, so that's something to watch out for.ShaunWhite wrote: ↑Tue Sep 27, 2022 12:13 pmMarket selection is absolutely fine if you don't fall foul of backfitting and don't try to do it in real time. There's often a lack of understanding about statistical relevance and sample size and people see a few losing weeks on say 'handicaps' and then assume they're not suitable.
If their main selling point is something as blatantly obvious as needing the right market for this strategy and then wishing you luck on finding those without teaching you how to find them, I'd look elsewhere.
