Well if we ignore the spread, its very simple to create a mean reversion strategy on exotic forex which looks insane, but spreads are so high that unless you add filters/other rules, it becomes uselss.
My personal best one so far is one that looks very similar in 3 major US indicies: Wall st, US tech, US 500. I only trade it in Wall st because the edge is biggest there. But seeing how well it performs (without spread added in any photos just so thats clear) does boost my confidence. Its been about 1 year out of sample.
Photo is 1* contract 1€, 1h timeframe.
