In the presence of multiple orders (one EA multiple charts, multiple EAs, manual trading,) while you are waiting for the current operation (closing, deleting, modifying) to complete, any number of other operations on other orders could have concurrently happened and changed the position indexing:
1. For non-FIFO (US brokers,) (or the EA only opens one order per symbol,) you can simply count down in a position loop, and you won't miss orders. Get in the habit of always counting down.
  Loops and Closing or Deleting Orders - MQL4 and MetaTrader 4 - MQL4 programming forum
2. For FIFO (US brokers,) and you (potentially) process multiple orders per symbol, you must count up and on a successful operation, reprocess all positions (set index to -1 before continuing.)
3. and check OrderSelect in case earlier positions were deleted.

4. and if you (potentially) process multiple orders, must call RefreshRates() after server calls if you want to use the Predefined Variables (Bid/Ask) or OrderClosePrice() instead, on the next order/server call.
```
OrderClose(OrderTicket(), OrderLots(), Bid, Slippage, MediumSeaGreen);
OrderModify(OrderTicket(),OrderOpenPrice(), OrderOpenPrice() + Point * MoveStopTo, OrderTakeProfit(), 0, Red);
```
Check your return codes for errors and report them.

         if (UseStopLoss) StopLossLevel = Ask - StopLoss * Point; else StopLossLevel = 0.0;
         if (UseTakeProfit) TakeProfitLevel = Ask + TakeProfit * Point; else TakeProfitLevel = 0.0;
```
You buy at the Ask and sell at the Bid.
- Your buy order's TP/SL are triggered when the Bid reaches it. Not the Ask.
- Your sell order's TP/SL will be triggered when the Ask reaches it. To trigger at a specific Bid price, add the average spread.
  MODE_SPREAD (Paul) - MQL4 and MetaTrader 4 - MQL4 programming forum - Page 3
- The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools -> Options {control-O} -> charts -> Show ask line.)
Using Points means code breaks on 4 digit brokers, exotics (e.g. USDZAR where spread is over 500 points,) and metals. Compute what a PIP is and use it, not points.

(Bars != BarCount)
```
For a new bar test, Bars is unreliable (a refresh/reconnect can change number of bars on chart,) volume is unreliable (miss ticks,) Price is unreliable (duplicate prices and The == operand. - MQL4 and MetaTrader 4 - MQL4 programming forum.) Always use time.
I disagree with making a new bar function, because it can only be called once per tick. A variable can be tested multiple times.

extern double Lots = 0;
```
Risk depends on your initial stop loss, lot size, and the value of the pair.
- You place the stop where it needs to be - where the reason for the trade is no longer valid. E.g. trading a support bounce the stop goes below the support.
- Account Balance * percent/100 = RISK = OrderLots * (|OrderOpenPrice - OrderStopLoss| * DeltaPerLot + CommissionPerLot) (Note OOP-OSL includes the SPREAD, and DeltaPerLot is usually around $10/pip but it takes account of the exchange rates of the pair vs. your account currency.)
- Do NOT use TickValue by itself - DeltaPerLot and verify that MODE_TICKVALUE is returning a value in your deposit currency, as promised by the documentation, or whether it is returning a value in the instrument's base currency (EUR, in this case).
  MODE_TICKVALUE is not reliable on non-fx instruments with many brokers.
- You must normalize lots properly and check against min and max.
- You must also check FreeMargin to avoid stop out
Most pairs are worth about $10 per PIP. A $5 risk with a (very small) 5 PIP SL is $5/$10/5=0.1 Lots maximum.

EA builder, fxDreema, EATree, FxPro Quant, MQL5 Wizard, etc. are all the same. You will get something quick, but then you will spend a much longer time trying to get it right, than if you learned the language up front, and then just wrote it.
- Since you haven't learned MQL4/5, therefor there is no common language for us to communicate.
  If we tell you what you need, you can't code it.
  If we give you the code, you don't know how to integrate it into yours.
  We are willing to HELP you when you post your attempt (using SRC) and the nature of your problem, but we are not going to debug your hundreds of lines of code. You are essentially going to be on your own.
- EA builder makes bad code counting up while closing multiple orders.
