Manually run an EA from fxcm MT4

Hi,

Sorry if it's the wrong ---um, I just registered and it seems this is the only ---um where I can post!!!

Anyway, I'm new to EA, I'd like to make a really simple EA where I can manually open a hedge positions using an EA.

I have this code that I adapted from the Internet:

Code:

---

#define MAGIC  12345
#define IDENT  " - EA Hedge Order"          // "mo_bidir_v0_1"

extern double  lots          = 5500;
extern double  stop_loss      = 2000;      // (80 pips) optimise 50-2000
extern double  take_profit    = 750;        // (75 pips) optimise 50-2000

int            last_bar      = 0;

int start()
{
  if (last_bar == Bars) return(0);

  last_bar = Bars;
  if (OrdersTotal() == 0)
  {
        int order_res;
        order_res = OrderSend(Symbol(), OP_BUY,  lots, Ask, 3, Ask - stop_loss * Point, Bid + take_profit * Point, "Buy" + IDENT, MAGIC, 0, Blue);
        if (order_res != -1) {
            OrderSend(Symbol(), OP_SELL, lots, Bid, 3, Bid + stop_loss * Point, Ask - take_profit * Point, "Sell" + IDENT, MAGIC, 0, Red);
        }
  }
  return(0);
}

The problem is: it's not clear how can I manually run the EA?

Thanks in avance!

PS. I need this to run via FXCM MT4 (using an fxcm-UK demo account)
