Any time frames is fine as long as you stick with one of them so that you can have a better reading in future.
This question has been asked millions of times. Many traders have their minds contaminated by professional talkers and writers. And that's why traders simply still don't get it. Which time frame to use depends on market conditions. For rapid market, use 1 minute (or even seconds ) chart. for slow market, use 5, 15 ... min chart. for very slow market, use etc etc etc Similarly for volume based chart. for rapid market, use small volume chart etc etc etc mind agility to choose the appropriate time frame chart is important. don't just fix on a particular time frame chart for entry.
Stop trading. Read The Man Who Solved the Markets. You will find your answer there if you read carefully. Then reach out to speedo. He knows how to get you fixed right up. Or, continue doing as you are doing and hope for the best.
Yes in my opinion TF usage shouldn't be static and should change depending on how the stock is moving, market conditions, how it fits your strategy/edge...
Ah, what does Jim Simons know...he and his algo's have only made hundreds of billions trading the 5 minute
I've used the 1-minute for daytrading the last 21 years for breakouts. I check the 5-minute when I see a possible reversal for hammer etc
