PositionModify, new stop loss fail

Vénon kirigaya  

Hello,

I can't understand why my positions don't change. The error is on the new stop loss. However, for the buy ask>new sl>last st and for the belly bid<new sl<last sl.

This SymbolInfoInteger(_Symbol,SYMBOL_TRADE_STOPS_LEVEL) say me that the minimum stoploss is 10 points so i put 11 for try but nothing change.

bool TraillingStop(double ask, double bid){
   for(int i = 0; i < PositionsTotal(); i++) {
      m_position.SelectByIndex(i);
      if(m_position.Magic() == MAGIC){
         if(m_position.PositionType()==POSITION_TYPE_BUY){
            if(m_position.PriceOpen()+sl_start*point_value<=ask && m_position.StopLoss()<SLAchat(ask,sl_trailling)){
               TradeManager.PositionModify(m_position.Ticket(),SLAchat(ask,sl_trailling),m_position.TakeProfit());
               Print("MODIFY: ask "+ask+" new sl "+SLAchat(ask,sl_trailling)+" ancien " + m_position.StopLoss());
            }
         } else if(m_position.PositionType()==POSITION_TYPE_SELL){
            if(m_position.PriceOpen()-sl_start*point_value>=bid && m_position.StopLoss()>SLVente(bid,sl_trailling)){
               TradeManager.PositionModify(m_position.Ticket(),SLVente(bid,sl_trailling),m_position.TakeProfit());
               Print("MODIFY: bid "+bid+" new sl "+SLVente(bid,sl_trailling)+" ancien " + m_position.StopLoss());
            }
         } else{
            Print("ERROR : Probleme avec le type de la position");
            return false;
         }
       }
    }
    return true;
}

Do you need normalize sl_trailing to not happen 148.82399999998 or 148.853000001?

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.)
              Double-precision floating-point format - Wikipedia, the free encyclopedia

    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.
              On 5Digit Broker Stops are only allowed to be placed on full pip values. How to find out in mql? - MQL4 programming forum (2011)

    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.

              Bid/Ask: (No Need) to use NormalizeDouble in OrderSend - MQL4 programming forum (2012)

  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.
              (MT4 2013)) (MT5 2022))

  6. MathRound() and NormalizeDouble() are rounding in a different way. Make it explicit.
              MT4:NormalizeDouble - MQL5 programming forum (2017)
              How to Normalize - Expert Advisors and Automated Trading - MQL5 programming forum (2017)

  7. Prices you get from the terminal are already correct (normalized).

  8. PIP, Point, or Tick are all different in general.

Thank you very much to all ! I'll try this as soon as I can ^^

I have done the normalisation but nothing has changed.

William Roeder, I will change my dots to ticks when I finish the first version of this robot

A Buy opens at Ask and closes at Bid. Likewise, Sell opens at Bid, closes at Ask.
