hello
i've created fibo with these codes
Inserted Code
#include <ChartObjects\ChartObjectsFibo.mqh>
CChartObjectFibo myFibo;
//....
myFibo.Create(0, "myFibo", 0, Time[t1], p1, Time[t2], p2);
//...
is it possible to get its angle - comparable with one given by trendByAngle ?

angle1 = MathArctan((p2 - p1) / (t1 - t2));
angle2 = MathArctan((p2 - p1)/ (Time[t2] - Time[t1]));
angle1 or angle2 give wrong values (in radians)

Thanks
I dont think using this formula will work because they are not the same unit. You have price in one axis and time in the other.
why dont you use the object trend by angle just to get that angle value ? (set it to color none)
ObjectCreate(chart_ID,name,OBJ_TRENDBYANGLE,sub_window,time,price,time2,price2)

and then

double angle=ObjectGet(name,OBJPROP_ANGLE);

After that, create an obejct text at P1 and Time1 with the condition if (angle > 90) angle = angle-360;
yeah that gives something
i'll check it more in my pg
tnx

maybe we've convert chart time & price coord. in x,y pixels to get correct angle value
use the gann angle trend line as your measuring stick.

Angles change when you zoom charts, slope doesn't. Perhaps you want to calculate the slope instead?
TradingView has a nice angle tool

Good, now zoom your chart and watch it epically fail. Angles are pointless in trading, slope on the other hand is not.
