Of course it is. You can't buy at the open order price (increasing lot size,) only at the current market price (open a new order.)

Depend on what you consider "order". Example mt4 vs mt5.
 

thanks guys for replay.. but you see im curious about this OrderClose.

 ill try this and not working.

OrderClose(Ticket,OrderLots()*2,Ask,slippage,DimGray);

but if i do this and its closing the order in half lot.

OrderClose(Ticket,OrderLots()/2,Ask,slippage,DimGray);

 both have the same error 131. im curious about why mt4 allowed to decrease the lots but not to increase it.

 

Asked and answered. Open a 0.01 lot order. Wait for the market to move 10 pips. Modify the order to 10000000 lots. Close the order and retire with your millions. It can't be done.

As for why your call fails - no mind readers here. What is Ticket? Have you done a successful OrderSelect (for OrderLots()?) Is it a sell order (Ask?) Is Ask fresh (no sleep/Server calls?) Is OrderLots()/2 a multiple of lotStep AND at least LotMin?

yes i have ECN Broker (Excel Market & ECN-FX Open) 

You can't open new trades with SL and TP.  ECN    Metatrader4

 What is  LotStep are you able to close it with half part ???  check out why it fails...

  

Still curious ??  What has to happen according to you if you  have open

0.1 BUY   OrderOpenPrice  1.30000    SL  1.29000     TP  1.31000 

and close this trade at   1.30500 with your command

OrderClose(Ticket,OrderLots()*2,OrderClosePrice(),slippage,DimGray);


 

 See also what happens if you try to do it manually.....

 yes i try that code and i have error 4051 & 131. so only pending order lot size can be modify.

in manual trade i use this "New Order" button & press "Copy" with different volume , SL=0, TP=0.

This "Copy" button on manual trade, how to use it in EA?

No. Asked and answered.

A pending order is not an open order. Make up your mind.

You use order send just like the first one. There is no such thing as a button in an EA.
 
thanks guys for clarification.
