Forex has higher volume than futures, and futures has higher volume than stocks, for the most part, 4hr and 1hr are not intraday, sure you can trade them but you will be playing with extreme low probability, the lower the timeframe the higher the probably for a short hold duration, most use 5mn and 15mn but the platform have access to they found it like dunking for apples, yes this is how most people trade. In Forex they found 1sc and 10sc (seconds) timeframes the most optimal (except the workload is beyond intense requiring specific lifestyle choices which very few could do, let alone sustain), for Stocks it is 1mn timeframe with an higher timeframe trend for direction because that is your friend. These provide higher probability outcomes which is proportionate to the amount of effort you put in and the quality of the fintech to offload analysis for decision making, as most put in little effort (lack of experience so no realtime pattern analysis) and have beyond useless fintech (it costs too much for realtime analysis) they have to push up the timeframes which lowers probability giving them a chance to unravel the mystery, by which time the markets have already moved on! Have been trading sub-minute today because the markets have decided to hibernate, well not exactly they are just using attrition for anyone trading minute up to weekly charts, inducing losses at those levels, unless you have low expectations which most do, because waiting is an expensive business.
