Why won't my robot buy at the right time?

[Mc Temple]

oid OnTick()

{
double parabolic = iSAR(_Symbol,_Period,0.02,0.2,0);
double KLine = iStochastic(NULL,0,5,3,3,MODE_SMA,MODE_MAIN,0,0);


 
  
if (OrdersTotal() == 0)
{  
if(KLine < 20 && Ask > parabolic)
{
OrderSend(_Symbol,OP_BUY,0.1,Ask,3,Ask-50*_Point,Ask+25*_Point,NULL,0,0,Green);
}
}


}

Guys help me. I am seriosu, this makes no sense.

It just doesn't buy when the right conditions is present.

EDIT : my bad you buy at Ask obviously, I don't see other errors though

[Keith Watford]

Jean Francois Le Bas:
you have to buy at Bid not Ask

No you don't, you buy at Ask.

[Jean Francois Le Bas]

Keith Watford:

No you don't, you buy at Ask.

oh yeah... my bad

maybe the stoploss is too close to the open price

you should add a verification with STOP_LEVELS

Check your parameters for iStochastic

double KLine = iStochastic(NULL,0,5,3,3,MODE_SMA,MODE_MAIN,0,0);

I think that you have price field and mode reversed.

yess, the text would be red if it was the right parameter

oid OnTick ()

{
 double parabolic = iSAR ( _Symbol , _Period , 0.02 , 0.2 , 0 );
 double KLine = iStochastic ( _Symbol , 0 , 5 , 3 , 3 , MODE_SMA ,STO_LOWHIGH, 0 , 0 );


 
  
 if ( OrdersTotal () <= 0 )
{  
 if (KLine < 20 && Ask > parabolic)
{
 OrderSend ( _Symbol ,OP_BUY, 0.1 ,Ask, 3 ,Ask- 50 * _Point ,Ask+ 25 * _Point , NULL , 0 , 0 ,Green);
}
}


}

try this

if doesnt work check conditions

 OrdersTotal () shows you if there are any open orders in your account. It doesn't matter whether the symbol is a buy order or a sell order.

OrderSend(_Symbol,OP_BUY,0.1,Ask,3,Ask-50*_Point,Ask+25*_Point,NULL,0,0,Green);

1. Always use strict. Fixing the warnings will save you hours of debugging, but you must understand the differences.

2. You would know why had you bothered to check your return codes, and report your errors (including market prices and your variables). Don't look at GLE/LE unless you have an error. Don't just silence the compiler, it is trying to help you.

3. You buy at the Ask and sell at the Bid.

   1. Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using the Ask±n, makes your SL shorter and your TP longer, by the spread. Don't you want the specified amount used in either direction?

   2. Your sell order's TP/SL (or Buy Stop's/Buy Limit's entry) will be triggered when the Ask / OrderClosePrice reaches it. To trigger at a specific Bid price, add the average spread.

   3. The charts show Bid prices only. Turn on the Ask line to see how big the spread is (Tools → Options (control+O) → charts → Show ask line.)
      Most brokers with variable spread widen considerably at end of day (5 PM ET) ± 30 minutes. My GBPJPY (OANDA) shows average spread = 26 points, but average maximum spread = 134 (your broker will be similar).

4. You are trying to make your SL 50 points minus the spread (say 30 points) or 20 points. You can't put them closer to the market than the minimum: MODE_STOPLEVEL * _Point or SymbolInfoInteger(SYMBOL_TRADE_STOPS_LEVEL).

   On some ECN type brokers the value might be zero (broker doesn't know.) Use a minimum of two (2) PIPs.
