Trade very small size and focus on your strategy/being profitable and not how much money you make in $ amounts. Don't think about making back your loss as much as thinking about trading well. Think of your loss as a lesson. If you can consistently make 50$/day with small size it means you are doing something right and you can scale it up
The question on which time frame to use is asked every week on ET. How about this one: What is the best time to end a time frame? If you select a 5-min time frame, where does that time frame should end? At (9:35, 9:40, 9:45,...), or, (9:36, 9:41, 9:46,...), or else (9:37:30, 9:42:30, 9:47:30, ...)? And on top of that, what would be the frequency of calculating your that time frame? Every minute, every 2 minutes? Ex: at 9:35 and 9:36 and 9:37, you get your 5 min time frame backward Food for thought...
That's what Amber said. "you can use any timeframe as long as you have a proper strategy to proceed with the trades."
Markets don't change in 1 sec. Most waves that you see take minutes to sometimes hours. There is a reason why professionals and HFT's are using 5 minute charts. And you try to beat them with 1 sec charts? You will be beaten.
