I've seen it used both ways. Right now i've got it set up as " extern int Slippage ". I have included the file <stdlib.mqh>. The command line I am using is the following. OrderSend(Symbol(),OP_BUYSTOP,Lots,dropped,Slippage,dropped-(SL*Point),dropped+(TP*Point),"simple buy stop",Green) Can I set it up as " extern double Slippage "? |

Two-Stage Modification of Opened Positions The two-stage approach allows you to avoid the unnecessary closing and re-opening of positions in situations close to the trend and in cases of possible occurrence of divirgence. |

int OrderSend( string symbol, int cmd, double volume, double price, int slippage, double stoploss, double takeprofit, string comment=NULL, int magic=0, datetime expiration=0, color arrow_color=CLR_NONE) No you can't set slippage as a double. |

Fractions of pips eh? Why would you want that? Am I missing something? CB |

Thanks for the answer and including the command string. This could come in handy in the future. In fact I've already printed it out. |

I've learned to make uncomplicated changes to programs by seeing how other programs are written that have coding for doing something that I want the program I am working on to do. When I saw the above slippage code written in different ways from 2 different programs I decided to ask. It looks as if one of the programs I was looking at has made a coding error. I suppose I should start to read the documentation on this site. |

Put very simply, "int" defines a variable which is a whole number whereas "double" defines a variable which is a number with decimal places. CB |

The wrinkle is the unit of slippage is points not pips so constants must be adjusted: //---- These are adjusted for 5 digit brokers. double pips2points = 1, pips2dbl, // = Point slippagePoints; // = SlippagePips * pips2points; int init() { pips2dbl = Point; if (Digits == 3 || Digits == 5) { pips2points *= 10; pips2dbl *= 10; } slippagePoints = SlippagePips * pips2points; } int start(){ //OrderSend(Symbol(), OP_BUYSTOP, Lots,dropped, //Slippage, dropped-(SL*Point), dropped+(TP*Point), //"simple buy stop",Green) OrderSend(Symbol(), OP_BUYSTOP, Lots,dropped, slippagePoints, dropped-(SL*pips2dbl), dropped+(TP*pips2dbl), "simple buy stop",Green) } |
