Error handling - freeze level

[altmql]

 I get this error: 

failed cancel order #10 sell stop 0.35 XAUUSD at 1310.86 sl: 1313.16 tp: 1308.56 [Invalid stops]

I assume it is because the price is too close to the order before the EA sends a request to delete the order. I use this function to delete orders, and I do check for freeze level, but I must be doing it wrong.

void PendingOrderDelete()
{
   ulong ticket = 0;
   double Ask = SymbolInfoDouble(_Symbol,SYMBOL_ASK);
   double Bid = SymbolInfoDouble(_Symbol,SYMBOL_BID);
  

   for(int i=0; i<OrdersTotal(); i++) {
      ticket = orderInfo.Ticket();

      if(!orderInfo.SelectByIndex(i))
         continue;
      if(orderInfo.Magic()!=inpMagicEA)
         continue;
      if(orderInfo.Symbol()!=_Symbol)
         continue;
         
      // Checking freeze level
      if(orderInfo.OrderType()==ORDER_TYPE_BUY_STOP)
        {
        double orderPrice = orderInfo.PriceOpen();
          if(orderPrice-Ask >= SymbolInfoInteger(_Symbol,SYMBOL_TRADE_FREEZE_LEVEL))
          {
            return;
           }
        }  
         if(orderInfo.OrderType()==ORDER_TYPE_SELL_STOP)
        {
        double orderPrice = orderInfo.PriceOpen();
          if(Bid-orderPrice >= SymbolInfoInteger(_Symbol,SYMBOL_TRADE_FREEZE_LEVEL)){
            return;
           }
        }  
                
      if(ticket!=0) {
         trade.OrderDelete(ticket);
      }
   }
}

Also, does anyone know if order expiration can cause this error? If by the time the order expires, the market is too close to the order to expire it, would that cause the same issue? In that case, I cant think of a way to check for that.. 

Hope someone can help me

Tick size vs Point(), can be a little tricky in Multicurrency EA

Fernando Carreiro, 2022.03.09 12:11

Tick Size and Point Size can be very different especially on stocks and other symbols besides forex.

Always use Tick Size to adjust and align your prices, not the point size. In essence, make sure that your price quotes, are properly aligned to the Tick size (see following examples).

...
double tickSize = SymbolInfoDouble( _Symbol, SYMBOL_TRADE_TICK_SIZE );
...
double normalised_price = round( price / tick_size ) * tick_size;
...
// Or use a function
double Round2Ticksize( double price )
{
   double tick_size = SymbolInfoDouble( _Symbol, SYMBOL_TRADE_TICK_SIZE );
   return( round( price / tick_size ) * tick_size );
};

double tickSize = SymbolInfoDouble( _Symbol, SYMBOL_TRADE_TICK_SIZE );

I changed to ticksize instead of point. But I still get the same error. Is there a way to get a more detailed explanation of why the errors happen during the validation process on mql5 market?

You can't move stops (or pending prices) closer to the market than the minimum: MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).

On some ECN type brokers, the value might be zero (the broker doesn't know). Use a minimum of two (2) PIPs.
