2 statement that contradict each other that I've heard many times, what's your opinion? - page 2

[Nikolai Semko]

What is a timeframe? It's just a different scale of price history.

A good strategy should not be tied to price scale, but only to price.

[Conor Mcnamara]

Every OHLC timeframe started on 1 second, and every tick timeframe started on 1 tick.  Couldn't you say the real ruler of the market direction is the composition of the first ticks or seconds?  In most trading software, 1 minute will be the first timeframe that you can view because there's a lot of noise below that. Some traders don't even look at charts at all. But the reason why both MTFs and HTFs can actually used (and useful) in trading strategies is because support, resistance and bounces exist (ATR, fibonacci retracement, market structure).

You’ve raised a great point. Both statements can be true: different strategies might perform better on different timeframes, yet confluence across multiple timeframes can validate a trading signal. Diversifying strategies across timeframes, rather than just currencies, can help manage risk and capitalize on various market behaviors. It’s all about finding the right balance and ensuring your strategy aligns with the specific characteristics of each timeframe.
