MQL4 - EA - Placing an order based on iCustom indicator - Order placement did not follow the signal correctly?

[insignificant83]

Hi all,

I'm trying to do these simple things, but I don't know why it didn't work:

1. Get a signal from iCustom indicator (Super-Arrow) for the 2 previous candle (shift 2 candles back),
2. When a buy signal emerges, then place a BUY order, and also draw a vertical line so that I can see if the open position matches the position of the signal.

However - when I backtested the EA, it appears to me that the BUY order (and VLINE) didn't align with the iCustom signal (GREEN ARROW), please see below.

As you can see below, the BUY order (and VLINE) didn't seem to align with the signal (GREEN ARROW), I don't know what did I do wrong.

Here's the code for the EA:

//+------------------------------------------------------------------+

void OnTick()
  {
   int op_result = 0;
   double buy = 0, sell = 0, tp_price = 0, sl_price = 0;
   buy = iCustom(_Symbol, 0, "super-arrow-indicator", 0, PreviousCandle);
   sell = iCustom(_Symbol, 0, "super-arrow-indicator", 1, PreviousCandle);

   if(OrdersTotal() == 0)
      if(buy != EMPTY_VALUE && buy > 0)
        {
         tp_price = Ask + NormalizeDouble(TakeProfitPoints * _Point, _Digits);
         sl_price = Ask - NormalizeDouble(StopLossPoints * _Point, _Digits);
         op_result = OrderSend(_Symbol, OP_BUY, Lots, Ask, SlippagePoints, sl_price, tp_price, NULL, 0, 0, clrGreen);
         CreateVerticalLine("BUY", clrYellow);
        }
  }
//+------------------------------------------------------------------+
//|                                                                  |
//+------------------------------------------------------------------+
void CreateVerticalLine(string lineName, color lineColour)
  {
   ObjectCreate(0,StringConcatenate("VLine_", lineName, "_", (string)TimeCurrent()),OBJ_VLINE,0,TimeCurrent(),0);
   ObjectSetInteger(0,StringConcatenate("VLine_", lineName, "_", (string)TimeCurrent()),OBJPROP_COLOR, lineColour);
  }
//+------------------------------------------------------------------+

And I have also attached both the EA source file and the indicator EX4 file.

Please if you could help or at least point out what was my mistake, that'd be greatly appreciated.

Thank you,

insignificant.
