How to put a stop loss at the moving average price?

[titosg]

Hi, I'm strating to code my first eas and I have a question.

I want to put a stop loss at the moving average price (a static stop loss, not tralling stop). I know it's a very basic question, but I've been looking for some tutorials for this and I haven't found anything.

Thanks

This is what I got right now

1. Your code	Documentation
   OrderModify( buyticket, 0, PREV*Point, Bid+TakeProfit*Point, 0 );	bool  OrderModify(    int        ticket,      // ticket    double     price,       // price    double     stoploss,    // stop loss    double     takeprofit,  // take profit    datetime   expiration,  // expiration    color      arrow_color  // color    );

   You can't modify the open price. Select the order and use OrderOpenPrice. You can not use any Trade Functions until you first select an order.
2. PREV is a price. Times Point is bogus.
3. Missing argument; does your code even compile?
4. Check your return codes for errors, and report them including GLE/LE, your variable values, and the market. That way we would know that at least you are calling your code.

   Don't look at GLE/LE unless you have an error. Don't just silence the compiler, it is trying to help you.

5.    OrderClose(OrderTicket(), OrderLots(), MarketInfo(_Symbol, MODE_BID+OrderType()), 10);

   No need for that garbage; just use OrderClosePrice. You can not use any Trade Functions until you first select an order.

6. OrderSelect(0, SELECT_BY_POS);

   Magic number only allows an EA to identify its trades from all others. Using OrdersTotal/OrdersHistoryTotal (MT4) or PositionsTotal (MT5), directly and/or no Magic number filtering on your OrderSelect / Position select loop means your code is incompatible with every EA (including itself on other charts and manual trading.)

The code is working fine, it does what I need. The only problem is that I don't know how can I add a stop loss at the PREV moving average price.
