FOMC Interest Rate Release

Why do we still fail to trade after learning so many trading indicators?

I have been unable to set the stop loss in the transaction, how can I do a good stop loss?

What do you think are the core competitiveness of a good broker?

I have had a few positions liquidated recently, but fortunately the losses were not very large. I would like to ask everyone, is there any way to prevent liquidation? Is there any trading discipline?

What kind of system can accurately locate support resistance and trend when doing transactions?
