Error code 130, invalid stops

 
OrderSend(_Symbol, OP_BUY,0.01,Ask,0,Ask-_Point*MarketInfo(_Symbol,MODE_STOPLEVEL),0);

I have checked the min stop lvl is 0.0003.  It works fine if I use a value >= 0.0005.

What's wrong?

Edit: It works if first I change sl to 0.0007 then compile. It works fine if it be decremented till and equal to 0.0005. 

But if I first change sl to 0.0005 or 0.0006 and compile, it gives invalid stop

Buys are closed at Bid, so the minimum stop must be calculated from the bid not ask. You should also include an allowance for possible slippage.

 

You buy at the Ask and sell at the Bid. Pending Buy Stop orders become market orders when hit by the Ask.

  1. Your buy order's TP/SL (or Sell Stop's/Sell Limit's entry) are triggered when the Bid / OrderClosePrice reaches it. Using 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 close to 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 spreads widen considerably at end of day (5 PM ET) ± 30 minutes.
    My GBPJPY shows average spread = 26 points, average maximum spread = 134.
    My EURCHF shows average spread = 18 points, average maximum spread = 106.
    (your broker will be similar).
              Is it reasonable to have such a huge spreads (20 pip spreads) in EURCHF? - General - MQL5 programming forum (2022)
