Which indicator from library is the bes for identify divergence? And second question, which indicators Nicolas use in trading?
You can use any oscillator to catch divergences with the price, there is no best one. A divergence occurs because indicators are calculated over X periods while this is obviously not the case for price.
Are there nonperiodical oscillators?
I don’t think so in the way you think about. 99% of indicators are calculated over an amount of periods. When you build an indicator, you only have 3 basics elements: time, price and volumes.
