Inserted Code
double EntryBuy = HighestPriceOfRange+(PipBox*Point);
   double EntrySell = LowestPriceOfRange-(PipBox*Point);
   double RangeSpan = HighestPriceOfRange-LowestPriceOfRange;
   double Additive = RangeSpan*0.5;
   double TakeProfit1 = (RangeSpan*0.2*Point);
   double TakeProfit2 = (RangeSpan*0.5*Point);
   double TakeProfit3 = RangeSpan;
   double StopLossBuy = LowestPriceOfRange+Additive;
   double StopLossSell = HighestPriceOfRange-Additive;

Having some trouble with this code. I am trying to get it to set my TP at 20%, 50%, and 100% of the recorded range size, in pips, plus a pipbox. The pipbox variable is the size of the envelope I set for above and below the range. Invariably, I need it to be part of the TakeProfit variables, but whenever I try to incorporate it, MT4 does a poltergeist on me and throws up 120mb log files filled with "error 130", or when it does work after fiddling, my TP is something absurd like 10.xxxx on GBP/USD. Why does it seem so hard to figure out something so simple?

The rest of the code functions as planned, it's only the take profit variables that are screwing up on me. Also, even though the StopLossBuy and StopLossSell variables print the same price, the code goes nuts if you don't separate them out like that.

First, price is already in Point, so when you multiply it with Point (again), well, you get the message.

Second, you forgot to NormalizeDouble()ed your price so it calculate the pipette as well and ruin everything.

Third, I can't really understand what's your EA doing base on what you posted, so that's all I could tell.

Fixed it! MT4 beat me for a while, but I finally got the upper hand, lol.

I had to expand the code out a bit, and section a lot of it, but it works now. Zen, spot on about the Point function. I removed the redundancy in the variables. I instead moved it so that the PipBox*Point function is now merely part of the take profit price on the ticket order. So now the take profit section of OrderSend says TakeProfitB1+(PipBox*Point) on buy order one, for instance.

Thanks for the quick reply. As for the NormalizeDouble function, that actually breaks the code. I thought the same as you until I started dabbling with it.

   double TakeProfitB1 = HighestPriceOfRange+Profit1;
   double TakeProfitB2 = HighestPriceOfRange+Profit2;
   double TakeProfitB3 = HighestPriceOfRange+Profit3;
   double TakeProfitS1 = LowestPriceOfRange-Profit1;
   double TakeProfitS2 = LowestPriceOfRange-Profit2;
   double StopLossBuy = LowestPriceOfRange+Additive;
   double StopLossSell = HighestPriceOfRange-Additive;
