Getting an error in while testing strategy "failed market buy 0.01 EUROUSD sl: tp: [Invalid stops]" MT5

Hi,

I have below code :

#include <Trade/Trade.mqh>



input double Lots = 0.02;

input double Lotfactor = 2;

input int TpPoints = 100;

input int SlPoints = 100;

input int Magic = 111;



CTrade trade;

bool isTradeAllowed = true;



int OnInit () {



   trade.SetExpertMagicNumber (Magic);





   return(INIT_SUCCEEDED);

  }



void OnDeinit(const int reason) {

  

  }



void OnTick() {



   if (isTradeAllowed) {

      double ask = SymbolInfoDouble(_Symbol,SYMBOL_ASK);

      double tp = ask + TpPoints + _Point;

      double sl = ask - SlPoints + _Point;



      ask = NormalizeDouble(ask,_Digits);

      tp = NormalizeDouble(tp,_Digits);

      sl= NormalizeDouble(sl,_Digits);



     if(trade.Buy (Lots,_Symbol,ask,sl,tp)) {

      isTradeAllowed = false;

      }

   }

 }

 

      void OnTradeTransaction (

      const MqlTradeTransaction& trans, //trade transaction structure

      const MqlTradeRequest& request, //trade transaction structure

      const MqlTradeResult&   result //trade transaction structure) 

   ) {

   

   if(trans.type == TRADE_TRANSACTION_DEAL_ADD) {

    CDealInfo deal;

    deal.Ticket (trans.deal);

    HistorySelect (TimeCurrent ()-PeriodSeconds (PERIOD_D1),TimeCurrent ()+10);

      if(deal.Magic() == Magic && deal.Symbol () == _Symbol) {

      if(deal.Entry () == DEAL_ENTRY_OUT) {

      Print (__FUNCTION__,"> Closed pos #", trans.position);

      if(deal.Profit () > 0) {

      isTradeAllowed = true;

      }else{

      

      if(deal.DealType () == DEAL_TYPE_BUY) {

      double lots = deal.Volume () * Lotfactor;

      lots = NormalizeDouble (lots,2);

    

   double ask = SymbolInfoDouble (_Symbol, SYMBOL_ASK);

   double tp = ask + TpPoints * _Point;

   double sl = ask + SlPoints * _Point;



   ask = NormalizeDouble(ask,_Digits);

   tp = NormalizeDouble(tp,_Digits);

   sl = NormalizeDouble(sl,_Digits);



   trade.Buy (lots,_Symbol,ask,sl,tp);

  }else if (deal.DealType () == DEAL_TYPE_SELL) {

  

   double lots = deal.Volume () * Lotfactor;

      lots = NormalizeDouble (lots,2);

    

   double bid = SymbolInfoDouble (_Symbol, SYMBOL_BID);

   double tp = bid - TpPoints * _Point;

   double sl = bid + SlPoints * _Point;



   bid = NormalizeDouble(bid,_Digits);

   tp = NormalizeDouble(tp,_Digits);

   sl = NormalizeDouble(sl,_Digits);



   trade.Sell (lots,_Symbol,bid,sl,tp);



     }

       }

     }

    }

   }

  }

You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit by the Ask.
1. Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?
2. Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger close to a specific Bid price, add the average spread.
  MODE_SPREAD (Paul) - MQL4 programming forum - Page 3 #25
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.)
  Most brokers with variable spreads widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).
You used NormalizeDouble, It's use is usually wrong, as it is in your case.
1. Floating point has a infinite number of decimals, it's your not understanding floating point and that some numbers can't be represented exactly. (like 1/10.)

  See also The == operand. - MQL4 programming forum (2013)
2. Print out your values to the precision you want with DoubleToString - Conversion Functions - MQL4 Reference.
3. SL/TP (stops) need to be normalized to tick size (not Point) — code fails on non-currencies.

  And abide by the limits Requirements and Limitations in Making Trades - Appendixes - MQL4 Tutorial and that requires understanding floating point equality Can price != price ? - MQL4 programming forum (2012)
4. Open price for pending orders need to be adjusted. On Currencies, Point == TickSize, so you will get the same answer, but it won't work on non-currencies. So do it right.

5. Lot size must also be adjusted to a multiple of LotStep and check against min and max. If that is not a power of 1/10 then NormalizeDouble is wrong. Do it right.

6. MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.

7. Prices you get from the terminal are already correct (normalized).
8. PIP, Point, or Tick are all different in general.

Help needed with invalid Cant find how to Distance between orders !

Cuneyt Ates 2023.09.29 06:59 #4

This EA is good... till crash ! Because lots starts 0.01 and goes to 60-80 lots !

Does anybody know the way close all positions for example ("last volume" >= "20 lot") ans start from 0.01 again ?
