The OBJ_ARROW itself, does not have that property, but you can easily add an OBJ_TEXT at the same anchor point with the text you desire, such as the value of the Arrow.
See the following for an example: https://docs.mql4.com/constants/objectconstants/enum_object/obj_text
OBJPROP_TOOLTIP |
The text of a tooltip. If the property is not set, then the tooltip generated automatically by the terminal is shown. A tooltip can be disabled by setting the "\n" (line feed) value to it |

if ( diff <= (-4.0) ) { ObjectCreate("UpSymbolBz"+i, OBJ_ARROW, 0, Time[i],vL+_Point+_Point); ObjectSet("UpSymbolBz"+i, OBJPROP_ARROWCODE, SYMBOL_ARROWUP); ObjectSet("UpSymbolBz"+i, OBJPROP_WIDTH,2); ObjectSet("UpSymbolBz"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolBz"+i, OBJPROP_ANCHOR, ANCHOR_TOP); ObjectCreate("UpSymbolBy"+i, OBJ_TEXT, 0, Time[i],vL+_Point+_Point+_Point+_Point); ObjectSet("UpSymbolBy"+i, OBJPROP_TEXT, diff); ObjectSet("UpSymbolBy"+i, OBJPROP_FONT,"Tahoma"); ObjectSet("UpSymbolBy"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolBy"+i, OBJPROP_ANCHOR, ANCHOR_TOP); }
Thanks, FMIC, for all your help. Tried a couple of options with DoubleToStr(), but still get same outcome.
if ( diff >= 4.0 ) { textB = DoubleToStr(NormalizeDouble(diff,5),1); ObjectCreate("UpSymbolAz"+i, OBJ_ARROW, 0, Time[i],vH+_Point+_Point); ObjectSet("UpSymbolAz"+i, OBJPROP_ARROWCODE, SYMBOL_ARROWDOWN); ObjectSet("UpSymbolAz"+i, OBJPROP_WIDTH,2); ObjectSet("UpSymbolAz"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolAz"+i, OBJPROP_ANCHOR, ANCHOR_BOTTOM); textA = "HERE Down"; ObjectCreate("UpSymbolAy"+i, OBJ_TEXT, 0, Time[i],vH+_Point+_Point+_Point+_Point); ObjectSet("UpSymbolAy"+i, OBJPROP_TEXT, textB); ObjectSet("UpSymbolAy"+i, OBJPROP_FONT,"Tahoma"); ObjectSet("UpSymbolAy"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolAy"+i, OBJPROP_ANCHOR, ANCHOR_BOTTOM); }
Here's the screen shot.
Use the ObjectSetString() not ObjectSet() with the "OBJPROP_TEXT". It is a string not a double.
You don't need NormalizeDouble() inside a DoubleToString(). It already has a "Digits" parameter. Also, DoubleToStr is the old MQL4 name. Use the newer name to be compatible with MQL5.
PS! Alternatively you can also use "ObjectSetText()" which sets various properties in one go.
textB = " "+ DoubleToStr(NormalizeDouble(diff,5),1); ObjectCreate("UpSymbolAy"+i, OBJ_TEXT, 0, Time[i],vH+_Point+_Point+_Point+_Point); ObjectSetText("UpSymbolAy"+i, textB); ObjectSet("UpSymbolAy"+i, OBJPROP_FONT,"Tahoma"); ObjectSet("UpSymbolAy"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolAy"+i, OBJPROP_ANCHOR, ANCHOR_LEFT); ObjectSet("UpSymbolAy"+i, OBJPROP_ANGLE, 90);
Maybe not the solution you want
Thank you FMIC and GumRai for all your help! You got me pointed in the right direction. After a bit of trial and error, and a little cheating, I got it.
Here is the working code. Not sure if there is a better or more correct way of doing this.
if ( diff >= 4.0 ) { ObjectCreate("UpSymbolAz"+i, OBJ_ARROW, 0, Time[i],vH); ObjectSet("UpSymbolAz"+i, OBJPROP_ARROWCODE, SYMBOL_ARROWDOWN); ObjectSet("UpSymbolAz"+i, OBJPROP_WIDTH,2); ObjectSet("UpSymbolAz"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolAz"+i, OBJPROP_ANCHOR, ANCHOR_BOTTOM); textB = DoubleToStr(NormalizeDouble(diff,5),0); ObjectCreate("UpSymbolAy"+i, OBJ_TEXT, 0, Time[i],vM); ObjectSetText("UpSymbolAy"+i, textB); ObjectSet("UpSymbolAy"+i, OBJPROP_FONT,"Tahoma"); ObjectSet("UpSymbolAy"+i, OBJPROP_COLOR,Lime); ObjectSet("UpSymbolAy"+i, OBJPROP_ANCHOR, ANCHOR_CENTER); ObjectSet("UpSymbolAy"+i, OBJPROP_ANGLE, 360); } if ( diff <= (-4.0) ) { textB = DoubleToStr(NormalizeDouble(diff,5),0); ObjectCreate("UpSymbolBy"+i, OBJ_TEXT, 0, Time[i],vN); ObjectSetText("UpSymbolBy"+i, textB); ObjectSet("UpSymbolBy"+i, OBJPROP_FONT,"Tahoma"); ObjectSet("UpSymbolBy"+i, OBJPROP_COLOR,Red); ObjectSet("UpSymbolBy"+i, OBJPROP_ANCHOR, ANCHOR_CENTER); ObjectSet("UpSymbolBy"+i, OBJPROP_ANGLE, 360); ObjectCreate("UpSymbolBz"+i, OBJ_ARROW, 0, Time[i],vL); ObjectSet("UpSymbolBz"+i, OBJPROP_ARROWCODE, SYMBOL_ARROWUP); ObjectSet("UpSymbolBz"+i, OBJPROP_WIDTH,2); ObjectSet("UpSymbolBz"+i, OBJPROP_COLOR,White); ObjectSet("UpSymbolBz"+i, OBJPROP_ANCHOR, ANCHOR_TOP); }
Here is the cheating, I had to do, to get the text above and below the arrows.
double vM = (vH + 0.0006); double vN = (vL - 0.0006);
Here's the screen shot.
As I stated before, "ObjectSetText()" can set several properties at a time, such as Font, Colour and also the text (thus saving you a few lines):
ObjectSetText("UpSymbolBy"+i,texB,0,"Tahoma",Red);

The following code allows you to place an arrow, at a specific candle, at a specific time. I wanted to know if there is a way to display a value, ( text ) above a down arrow and below an up arrow? Which will signify the value at that point.
