1. How can I tell if start is being called the first time in an EA?
bool FirstTime = True; int start(){ if(FirstTime == True){ Print("This is the first time"); FirstTime = false; }
1-a. Is there a way you can tell which day you're on (Bars-1 or 0, eg).
Typically, you are "on" the bar that you specify in your code.
2. If I have more that one buy of EUR/USD (eg) how can I calculate the average cost of my position given what I paid for each order and the lot size of that order?
You can determine the "breakeven" price, if that is what you mean by "cost".
For each order:
cost1 = lots * price
cost2 = lots * price
costn = lots * price
---
breakeven = (sum of cost1 through costn ) / total lots
--
example: 2 lots at $3, 4 lots @ $4 = (6 + 16) / 6 = $3.667
