| Post subject: | Calculate Open Positions by MQL icon |
Hi there, Supposed I have EA for EurUsd, GbpUsd and NzdUsd. They are attached to their own chart respectively. Supposed due to co-relation issues I want the other two to NOT trade when a position by any one is entered. I was told to use 'CalculateOpenPosition' by the MQL icon. How is this done? Any diagrams to show? |

If you want to use MQL you need to open a generated ea with MetaEditor and understand how it works From a generated EA I got this: if (CalculateOpenPositions(symbol_bn,ordertype_bn,magic_bn)>=MaxNumberofPositions) { Print("I-Warning : Can not execute new ",OrderTypetoString(ordertype_bn)," order for Symbol ",symbol_bn,". Maximum number of ",MaxNumberofPositions," open positions reached."); return(0); } In the MQL icon in version 3.2 or higher (won't work in old versions) you need to put something like: CalculateOpenPositions(symbol_bn,ordertype_bn,magic_bn)>=MaxNumberofPositions You need to replace symbol_bn,ordertype_bn,magic_bn and MaxNumberofPositions with your own info Like CalculateOpenPositions("EURUSD",OP_BUY,your ea magic number)>=1 unfortunately we do not do MQL support here or teach MQL - we only do product support so you have to do a lot of try and error on your end. We do not have any examples but I have seen some posts in the forum with some MQL code |

I have this question. symbol_bn may refer to EURUSD if I have one EA only. But if I have many EAs for pairs ending with USD do I define them all or is there a shorter way like xxxUSD? |

Unfortunately if you want to use the MQL icon you need to understand MQL a bit If you want to check 2 pairs, you need to use an AND CalculateOpenPositions("EURUSD",OP_BUY,your ea magic number)>=1 && CalculateOpenPositions("GBPUSD",OP_BUY,your ea magic number)>=1 |
