Surely there are different types of SUCCESSFUL traders just as in life.
To ask a flambouyant character to behave like a mindless computer is probably asking too much.
Yes it suits the dull boring accountancy types but who wants to be dull and boring by choice ?
Be yourself imho. Suit yourself.
You can enter you these details through your normal MT4/5 platform.
You can set your stop loss and take profit when you enter a trade, or use a trailing stop if you prefer.
Or set up a pending order to enter automatically when it reaches your desired level, and within this you can set SL and TP as well.
Not sure if that helps, or if I have misunderstood.
This is good in theory, but everyone works out personal rules. Also when we are talking about the risk management, way to deal with the emotions we need to keep in mind that this is very individual and varies on the background, experience, soft skills and even the plan you set up.
