OrderModify()

i am using a "Switch" function to modify the open order at each profit level,(each case # represents the amount of profit) however for some reason the ModifyOrder() function is not working, i have the order selected properly and i am entering the case function properly becuase when i take the actual modifyOrder operator that is supposed to change the stoploss and replace it with a Alert() the Alert() is working, so i am able to deduce that everything is working properly except for the way that i am using the ModifyOrder() function.

this is what my switch function from the EA i wrote looks like:


if(OrdersTotal() > 0 && OrderSelect(0, SELECT_BY_POS)==true && A==1)
{
switch(OrderProfit())
{
case 0 : OrderModify(OrderTicket(),OrderOpenPrice(),OrderStopLoss()-4,OrderTakeProfit(),0,Blue); break;
case 1 : Alert ("profit is 1"); break;
case 2 : Alert ("profit is 2"); break;
case 3 : Alert ("profit is 3"); break;
case 4 : Alert ("profit is 4"); break;
case 5 : Alert ("profit is 5"); break;
case 6 : Alert ("profit is 6"); break;
case 7 : Alert ("profit is 7"); break;
case 8 : Alert ("profit is 8"); break;
case 9 : Alert ("profit is 9"); break;
case 10 : Alert ("profit is 10"); break;
case 11 : Alert ("profit is 11"); break;
}

what am i doing wrong in the OrderModify()?


am i entering the ticket, openprice and stoploss wrong?


my EA only allows for a max of 1 order open at a time.


mabye someone could direct me to some literature that is very detailed about OrderModify() and OrderClose() i am prettysure i have read just about everything over at book.mql4.com and it didnt help me

i just added the "get last error" fuction after the modify order that isnt working and i got error 4063 which means "integer parameter expected"

any ideas?

and when i do this :

OrderModify(OrderTicket(),OrderOpenPrice(),(OrderStopLoss()- 2),OrderTakeProfit(),Blue) ;

i get error 4051 which means "invalid function parameter value"


and when i change it to this :

OrderModify(OrderTicket(),OrderOpenPrice(),(OrderStopLoss()+ 2),OrderTakeProfit(),Blue) ;

- all i did was change the subtraction sign to a addition sign-

and i get this error: 130 " invalid stops"

OrderProfit returns the profit in the deposit currency, not the amount of pips.

double OrderProfit( )Returns the net profit value (without swaps or commissions) for the selected order. For open positions, it is the current unrealized profit. For closed orders, it is the fixed profit.
Returns profit for the currently selected order.
Note: The order must be previously selected by the OrderSelect() function.

for somereason order profit is still working fine for me.

oh it is because i am using .1 lots on eurusd so 1 pip is an even 1 dollar so everything works out fine
