Yes sir, you can easily do this using MT5 chart objects.
The best approach is to create a reusable helper function that draws the required object whenever your strategy generates a signal.
You only need to create this function once, and then call it wherever your Buy or Sell conditions are satisfied.
You can place the following function anywhere above your OnTick() function.
//+------------------------------------------------------------------+
//| DRAW OBJECT ON CHART |
//+------------------------------------------------------------------+
void DrawObject(string prefix, datetime time, double price, string objectType, color objColor, int width = 1, string text = "")
{
// Create unique name
string name = prefix + "_" + IntegerToString((int)time) + "_" + IntegerToString(rand());
// Delete existing object if any
if(ObjectFind(0, name) >= 0)
ObjectDelete(0, name);
// Create arrow object
if(!ObjectCreate(0, name, OBJ_ARROW, 0, time, price))
return;
//--- Set arrow code based on type
if(objectType == "arrow_up")
ObjectSetInteger(0, name, OBJPROP_ARROWCODE, 233); // Up arrow
else if(objectType == "arrow_down")
ObjectSetInteger(0, name, OBJPROP_ARROWCODE, 234); // Down arrow
else if(objectType == "flag")
ObjectSetInteger(0, name, OBJPROP_ARROWCODE, 79); // Flag
else
ObjectSetInteger(0, name, OBJPROP_ARROWCODE, 234); // Default Down arrow
//--- Set properties
ObjectSetInteger(0, name, OBJPROP_COLOR, objColor);
ObjectSetInteger(0, name, OBJPROP_WIDTH, width);
ObjectSetInteger(0, name, OBJPROP_BACK, false);
ObjectSetInteger(0, name, OBJPROP_SELECTABLE, false);
ObjectSetInteger(0, name, OBJPROP_HIDDEN, false);
//--- Tooltip
ObjectSetString(0, name, OBJPROP_TOOLTIP, objectType + " at " + TimeToString(time, TIME_DATE | TIME_MINUTES | TIME_SECONDS));
}
Now, whenever your Buy condition is satisfied, simply call the function like this:
double arrowPrice = breakoutLow - PipsToPoints(ArrowPips);
DrawObject("Signal", breakoutTime, arrowPrice, "arrow_up", clrLime, 2);
Similarly, for a Sell signal, you can draw a down arrow:
double arrowPrice = breakoutHigh + PipsToPoints(ArrowPips);
DrawObject("Signal", breakoutTime, arrowPrice, "arrow_down", clrRed, 2);
That’s it.
Whenever your strategy generates a signal, simply call DrawObject() with the appropriate parameters, and MT5 will plot the symbol on the chart automatically.
You can also customise the symbols by changing the OBJPROP_ARROWCODE values. MT5 supports many different Wingdings symbols such as arrows, flags, stars, circles, check marks, and more.
The DrawObject() function shown above is a reusable helper built using the official MQL object documentation. You can explore all available symbol codes here:
–https://docs.mql4.com/constants/objectconstants/wingdings
You can replace the arrow codes with any Wingdings code you like to display different symbols on your chart. This makes it easy to visually mark breakouts, entries, exits, reversals, or any other event generated by your strategy.
