Question #5: You have opened position, lets say 0.01 lot long eurusd. It is currently in the loss of 100.0 pips.
What are all options you can do to close trade(s) at profit?
Using no SL & waiting for the reverse of the market! Correct or anything else?
That is one option.
Another is adding more trades of the same direction so more long trades. That is what is called averaging as you get better price closes to market.
Adding more trades with higher amount is martingale.
And another option is to take opposite direction trade which is called hedging and closing each position once market reach its price.
Last option another trade, opposite direction, higher amount.
So there is always a solution, even accepting the loss is an solution. You should decide based on your trading plan
