Need code example for displaying SYMBOL_LEFTPRICE

New comment
 

Hello,

Can someone please provide a code example on how to display the SYMBOL_LEFTPRICE symbol on the chart window on any bar at any price?

What function will place this arrow on the chart?

Thank you.

Read documentation, please. Fucntion ObjectCreate will help you. Also https://docs.mql4.com/constants/objectconstants/enum_object:

Object type identifier constants used with ObjectCreate(), ObjectsDeleteAll() and ObjectType() functions. It can be any of the following values:
Objects can have 1-3 coordinates related to type.

Constant Value Description
OBJ_VLINE0Vertical line. Uses time part of first coordinate.
OBJ_HLINE1Horizontal line. Uses price part of first coordinate.
OBJ_TREND2Trend line. Uses 2 coordinates.
OBJ_TRENDBYANGLE3Trend by angle. Uses 1 coordinate. To set angle of line use ObjectSet() function.
OBJ_REGRESSION4Regression. Uses time parts of first two coordinates.
OBJ_CHANNEL5Channel. Uses 3 coordinates.
OBJ_STDDEVCHANNEL6Standard deviation channel. Uses time parts of first two coordinates.
OBJ_GANNLINE7Gann line. Uses 2 coordinate, but price part of second coordinate ignored.
OBJ_GANNFAN8Gann fan. Uses 2 coordinate, but price part of second coordinate ignored.
OBJ_GANNGRID9Gann grid. Uses 2 coordinate, but price part of second coordinate ignored.
OBJ_FIBO10Fibonacci retracement. Uses 2 coordinates.
OBJ_FIBOTIMES11Fibonacci time zones. Uses 2 coordinates.
OBJ_FIBOFAN12Fibonacci fan. Uses 2 coordinates.
OBJ_FIBOARC13Fibonacci arcs. Uses 2 coordinates.
OBJ_EXPANSION14Fibonacci expansions. Uses 3 coordinates.
OBJ_FIBOCHANNEL15Fibonacci channel. Uses 3 coordinates.
OBJ_RECTANGLE16Rectangle. Uses 2 coordinates.
OBJ_TRIANGLE17Triangle. Uses 3 coordinates.
OBJ_ELLIPSE18Ellipse. Uses 2 coordinates.
OBJ_PITCHFORK19Andrews pitchfork. Uses 3 coordinates.
OBJ_CYCLES20Cycles. Uses 2 coordinates.
OBJ_TEXT21Text. Uses 1 coordinate.
OBJ_ARROW22Arrows. Uses 1 coordinate.
OBJ_LABEL23Text label. Uses 1 coordinate in pixels.


and Arrow codes:

Predefined Arrow codes enumeration. Arrows code constants. It can be one of the following values:

Constant Value Description
SYMBOL_THUMBSUP67Thumb up symbol (C).
SYMBOL_THUMBSDOWN68Thumb down symbol (D).
SYMBOL_ARROWUP241Arrow up symbol (ñ).
SYMBOL_ARROWDOWN242Arrow down symbol (ò).
SYMBOL_STOPSIGN251Stop sign symbol (û).
SYMBOL_CHECKSIGN252Check sign symbol (ü).

Special Arrow codes that exactly points to price and time. It can be one of the following values:

Constant Value Description

1Upwards arrow with tip rightwards (↱).

2Downwards arrow with tip rightwards (↳).

3Left pointing triangle (◄).

4En Dash symbol (–).
SYMBOL_LEFTPRICE5Left sided price label.
SYMBOL_RIGHTPRICE6Right sided price label.

Rosh, I assure you the issue has nothiong to do with me being lazy....

I have NEVER been able to get the system to displa SPECIAL ARROW CODES... if you notice the values are shared by other constants... so, I merely requested a code example for SYMBOL_LEFTPRICE that is known to work.

Rosh,

Thank you so much! I was able to see my error.... I wasn't doing the ObjectSet.... was placing SYMBOL_LEFTPRICE in the ObjectCreate line...!

ObjectCreate(arrowName,OBJ_ARROW,0,Time[0],Open[0]);
ObjectSet(arrowName,OBJPROP_ARROWCODE,SYMBOL_LEFTPRICE);

 
You are welcome.
