To adjust the indicator to your requirements and traded intervals, you need to look at the initial Fibo Bars 2, which will be considered an older trend for you. After that, on the lower Fibo Bars 2 periods, see what corrections you want to trade, and what will be considered a reversal for you.
The settings are very flexible, if you use oscillators when Fibo Bars 3 is colored yellow, you can find even earlier entry points. You can hold a trade either until the oscillator is overbought / oversold, or until the yellow color reappears on Fibo Bars 3.
