Kardec Trader explains why traders get confused: they mix up analysis timeframes, where you identify key levels, with trigger timeframes, where you enter. Swing traders should analyze weekly and daily, then trigger on daily. Intraday traders analyze daily and 60-minute, then trigger on 15-minute. Keeping these separate makes it easier to measure what actually works.

This is where I see a lot of traders struggle is time frame. I've got my discretionary analysis process where I'm determining the market condition. I've got analysis time frames and then what I'm going to have is trigger time frames. If I'm looking at a swing trade setup weekly and daily, that's where I'm going to establish my key levels, what I call the proceed with caution level, where I've only got one high. My trend line is primarily going to be on the daily and then the trigger time frame for that is the daily. So if you're looking as an intraday trader, you want to be looking at your daily, your 60 and then your trigger time frame for where your trend line and your break of your trend line would be probably something like a 15 minute. So in that scenario I can tell you straight away that the data that backs this up works. I can't tell you there, there's nobody I know that's trading that. If you can keep your time frame, say right, these are time frames I do the analysis on. These are time frames, take the trades on it makes it much easier to measure.
