-1 is not the error . . . -1 is the return value meaning the OrderSend failed . . . read the Documentation

Add a Print if iReturnOrder is < 0 and Print GetLastError()

It may well be an ECN Broker issue . . . . if it is there is plenty of info here: ECN

Why ?

Did you still install at C:\Program Files\ on 7/Vista ? The other you can't even open chm help files ?

 

Do what RaptorUK said, check GetLastError(). I think you should change some parameter :

    ,Bid-150*Point, Ask+150*Point);

You probably sending order with TP and SL within broker STOP_LEVEL. Look for MarketInfo.

 

I can see two reason why the OrderSend in your code would return a -1.

First, if you are dealing with an ECN broker, you must use OrderSend without setting a stoploss or takeprofit (that is, make those values = 0). Once the order has been successfully placed, modify the order (using OrderModify) to set the stoploss and takeprofit values.

Second, if you are dealing with a 5 digit broker, Point will be 0.00001. In your code, that means you are trying to set a stoploss and takeprofit of 1.5 pips (15 points). This value (15 points; aka, 1.5 pips) may be inside the broker's stoplevel, and if so, the broker will reject the trade. See Requirements and Limitations in Making Trades. If you want a 15 pip stoploss and takeprofit and are dealing with a 5 digit broker (and therefore Point is 0.00001), your code should be:

int iReturnOrder = OrderSend(Symbol(),OP_BUY,0.1,Ask,3,Bid-150*Point,Bid+150*Point); 

Out of curiosity, why are you using the Bid price (rather than the Ask price) when calculating your stoploss and takeprofit prices?

Hope the above helps.
