Take Profits and Stop Loss is Int Value or Double Value?


extern int TP = 100;
extern int SL = 100;

//OR

extern double TP = 100;
extern double SL = 100;

// ********************************************** //

extern int Slippage = 3;
pipettes = Point;

double TakeProfit_BuyEntry = (TP != 0) ? (Ask + TP * pipettes) : 0;
double StopLoss_BuyEntry = (SL != 0) ? (Ask - SL * pipettes) : 0;
OrderSend(Symbol(), OP_BUY, Lot_Size, Ask, Slippage, StopLoss_BuyEntry, TakeProfit_BuyEntry, (BuyLimitTradeComment + trades_count(BuyLimitMagic)), BuyLimitMagic, 0, White);
 
  1. anuj71: Take Profits and Stop Loss is Int Value or Double Value?

    They are prices (double)

  2. double TakeProfit_BuyEntry = (TP != 0) ? (Ask + TP * pipettes) : 0;
double StopLoss_BuyEntry   = (SL != 0) ? (Ask - SL * pipettes) : 0;

    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 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 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)

If we use like this, we can use double 


double Pips;  
if(Digits == 3 || Digits == 5)
      Pips = 10.0 * Point;
   else
      Pips = Point;


But if we are using directly point (Smallest value of currency pair), For TP and SL the int is appropriate. because having TP 1.5 makes no sense because the lowest point we targeting? 


double Pips;  
 Pips = Point;
