It surprises me that even "veteran" traders question whether some random guy they've never met online has an edge or not just based on what they see on their timeline.
I will NEVER pass judgement on another traders style or the tools they use. If it works for them on a consistent basis year over year... great for them.
Order flow, trendlines, volume, ICT, moving averages, RSI, bollinger bands, macd, can all work when in the right hands.
There are people out there using totally obscure things like moon cycles to express their ideas in the markets.
Just because other people fail at using it, doesn't mean EVERYONE will.
You shouldn't let ANYONE tell you your methods don't hold up.
Only you know how much work took place behind the scenes.
