To catch more mosquitoes and collect more mushrooms... Sometimes I go lower than M1. For example, 20 seconds, each candle.
Someone mentioned: remove all indicators from the chart. From Rok it's 5 seconds, candle. You won't be able to tell what time frame you're on. So, the trend depends on what you're looking at at the moment. It depends on whether you want to catch long movements with a small % of your balance, or you want to catch short movements with a larger % of your balance. It's all an individual approach. There's no one golden rule. You decide. And everything that's impossible is impossible until it becomes possible
