hello, i'm trying to add custom levels to a Pitchfork as described here: https://docs.mql4.com/constants/objectconstants/enum_object/obj_pitchfork
ObjectCreate(0,'Pitch0',OBJ_PITCHFORK,0,ZZTime[3],ZZPrice[3],ZZTime[2],ZZPrice[2],ZZTime[1],ZZPrice[1]);
ObjectSetInteger(0,'Pitch0',OBJPROP_COLOR,clrRed);
ObjectSetInteger(0,'Pitch0',OBJPROP_STYLE,2);
ObjectSetInteger(0,'Pitch0',OBJPROP_LEVELS,4);
ObjectSetDouble(0,'Pitch0',OBJPROP_LEVELVALUE,0,0.5);
ObjectSetDouble(0,'Pitch0',OBJPROP_LEVELVALUE,0,-0.5);
ObjectSetDouble(0,'Pitch0',OBJPROP_LEVELVALUE,0,1);
ObjectSetDouble(0,'Pitch0',OBJPROP_LEVELVALUE,0,-1);
I can see the pitchfork but i can't see any level. what's wrong?
thanks in advance

Did you follow example exactly as presented in MQL4 docs?
https://docs.mql4.com/objects/objectsetdouble
I think same principles in code apply to Pitchfork as well.
Specifically there is some places where you should check that your MQL4 API call succeeded or Print GetLastError() on error.
And sometimes forgetting to call ChartRedraw() makes you believe that your code is not working even though it's just a repainting problem (like on weekends).
And fourth parameter ('prop_modifier') in your example is always zero (0) so it seems that you are actually modifying level 0 value four times using value 0.5, -0.5, 1.0 and -1.0.
Last value -1.0 should be the effective value.
'prop_modifier':
[in] Modifier of the specified property. It denotes the number of the level in Fibonacci tools and in the graphical object Andrew's pitchfork. The numeration of levels starts from zero.

Being Bearish or Bullish Makes No Difference

hi,
i tried everything, but won't work
i can draw levels for fibochannel but not for pitchfork.
i tried to copy and paste the whole metaquotes page ( https://docs.mql4.com/constants/objectconstants/enum_object/obj_pitchfork ) but still won't work..
i don't understand..... now i added levels using obj_trend..
i really appreciated your help, thanks anyway 😉
best regards
