what timeframe should i trade?

Price action can vary in different timeframes. In longer term timeframes the price action and fundamentals are much more clear. Unfortunately it would take a very long time to figure out whether or not what you’re doing is successful on longer timeframes. In shorter timeframes you can often tell very quickly if what you’re doing is profitable. Unfortunately there’s a lot more “noise” on these levels which can prove deceptive for those trying to learn. Therefore the best bet is to use a multi-timeframe analysis, working from top-down to come up with trades.
