How to Fix Please Verify Operation Parameters in MT4?

by Fxigor

If you use Expert advisors very often, you can see errors like this: “Please verify operation parameters and try again later.” This Order sends error three is very dangerous because this error blocks future trades from being executed, and Expert advisors become useless.

The OrderSend Error 3 or invalid trade parameters in MT4 is called ERR_INVALID_TRADE_PARAMETERS, and it is often an error such as a common error in MT4.

Why do invalid trade parameters errors in MT4 occur?

Invalid trade parameters errors in MT4 occur because one of the following reasons:

  • If MQL programmer types incorrect operation in OrderSend() function.
  • Wrong defined slippage in input. Slippage needs to be 0 or greater.
  • Order is not defined well because incorrect order tickets are passed on the function OrderModify(). Add piece of code “if (ticket > 0)” before OrderModify().

In OrderSend() function you can define only 6 operations:

  • OP_BUY will Open a long position.
  • OP_SELL will Open a short position.
  • OP_BUYLIMIT will open a buy limit order.
  • OP_SELLLIMIT will open a sell limit order.
  • OP_BUYSTOP will open buy stop order.
  • OP_SELLSTOP will open sell stop order.

How to Fix Please Verify Operation Parameters in MT4?

To fix invalid trade parameters error in MT4 marked as ERR_INVALID_TRADE_PARAMETERS, you need first to check-in the MQL code is slippage positive number defined in the input. If slippage is positive number, then you need to check the ticketing system in MQL, and you need to add if (ticket > 0) in front of the OrderModify() function such as:

if (ticket > 0)
OrderModify()…..

Usually, if you have this error, the problem is in the expert advisor code, and you can ask the programmer for help. Please see all major errors in MT4 below:
