Candle by candle, yes. But once a moving average or stochastic changes direction it’s obviously not 50-50 whether it continues in that direction. Otherwise I wouldn’t get all those nice coloured lines making peaks and troughs. That’s the kind of trend I’m talking about. There’s really only 3 options, trending up, trending down or deeply annoying choppy sideways (not counting the crazy 200pt moves on breaking news or a Trump tweet). Can’t understand why it’s so hard to find a combination of variables that deal well with these 3 basic situations that you find again and again on all timeframes.

But what’s your approach to optimization then? You do a 70/30 WF with as much data as you can get, let’s say the OS performance is -86%, +108, +12, -33, +42. Then what?
