I will try to exemplify what I am asking.
Lets assume, we open a Buy 0.01 EURUSD at 1.3000 (TRADE 1)
It goes negative by 120 pips (1.288)
Here at this point, we will open a new trade, which is 4 times the lot size of TRADE 1, with a TP of 30 pips, 20 pips to breakeven TRADE 1 and 10 pips for its own TP.
My question is : what will be the lot size and will 0.01 (TRADE 1) will close at 0 when Trade 2 opens ?
Your question isn't clear. If lot size is 4 times that of TRADE1 then you can't meet your others requirements (30, 20, 10). If you ask "what lot size" then it's not 4 times that of TRADE1, and it's probably not possible to meet all others requirements simultaneously. The second question I don't even understand it (how a trade with 120 pips in loss can close at 0 by opening an other trade ???)
Thanks for your reply. Yes I figured it out myself. The lot size for 2nd trade is 0.05 [(0.01 x 4) + 0.01], and when the 2nd trade opens, the first 1 closes at zero (according to MT5 Order Management System) because the 2nd trad eis also Buy like first one.
