@Andi- I’ve been experimenting using the next two higher timeframes. So if Entry is on the M15 I use M30 and H1 trending following indicators. I think the magic is in locking indicators we understand and giving the builder 2 or 3 additional slots to filter the logic on the entry timeframe. I used to use RSI looking for it to be in extremes on the oversold or bought but trying catch reversals like that is tough. Hard to wait for the stars to align on multiple tf’s if that’s what you’re asking.
Just recently i turned my attention to indicators i use in my discretionary trading to tell the builder what direction i want it to go (since that’s when i’d be hawk eyeing the market for an entry), then letting it filter out the false signals on its own.
