As Vonasi is saying it all depends on ur strategy. There is no right or wrong answer, ur strategy might be done within 10 minutes, or 10 days. All depends on ur entry and exit. There is no “1 way to trade and THIS is how u do it!!”
Just test everything and nothing and see what happens. If it looks robust and good shit, put it in demo 1-2 months and see what happens. if it behaves just like backtest just put it live and pray to jebus! 😀
Edit: Can also add that Smaller timeframe = more trades, more noise, more fake signals
while Larger timeframe gives less noise, less opportunities and less fake signals
This is obvious… Just check out the different timeframes and find the one u wanna trade. again there is no right or wrong answer. I could never trade on 1 min cus its just way way too much. At the same time i dont have any daily strategies cus i think its too slow. So i like to work in 15m, 30m and 1h! But if i dint something that looks great on 4 h its not like i wouldnt run it hehe 🙂
