how many timeframes of alignment is too many?

[Shadow Trader]

Four screens, four timeframes, all pointing the same way. It looks bulletproof, and it also takes ages to arrive. Before adding a fifth, a few questions are worth asking:

- Does each added timeframe filter out losers, or just trades?
- If the 1-minute and 5-minute already agree, what does the 15-minute add?
- How many setups a day survive full alignment?
- By the time everything lines up, how much of the move has already happened?
- Are the timeframes independent at all? A 5-minute candle is built from the same ticks as five 1-minute candles, so the charts are strongly related.

That last point gets skipped a lot. Stacking timeframes can feel like collecting separate opinions, when it's really one stream of prices drawn at different zoom levels. Agreement between them says less than it seems to.

Higher-timeframe agreement mostly tells the dominant drift, and two or three charts usually cover that. Past that, extra confirmation tends to thin out the sample without clearly improving it. Fewer trades, same win rate, more commission.

How many timeframes do you require before pulling the trigger, and did cutting one ever improve the results?
