as for myself I actually never make a profit with mistakes and also the reason is when I see myself on the wrong side because my trade is almost out of trade while not taking sufficient time as a result of my apprehend delay can be very dangerous Therefore Based mostly for this I really never make a profit with mistakes as a result of I do not want to take a lot of risk across the market Yes I have even created a profit with errors too. finally barely made it because it was given to me. if I trade in any other way then I may have a loss. Therefore generally luck happens in forex, though not very common, therefore we should not rely on luck for our special advantage. generally other luck can also happen.
