Create Draw Fib using Button

[BartMan]

I have code where I create a Fib retracement it works in on bar update, I created a method to create the fib and then copied to run on button press, The button does execute but Throws an unhandled exception index out of range on creating the FIB, I have tried to revert to the documentation method. I have created the fib object outside of the button action My guess is it must need an event handler. I wish to use a scalping method and want the Fib and order placed based on said fib.

I am using the documentation

// Instantiate a FibonacciRetracements object
FibonacciRetracements myFibRet = Draw.FibonacciRet racements(this, "tag1", true, 10, Low[10], 0, High[0]);

// Set the object's lines to extend to the right
myFibRet.IsExtendedLinesRight = true;

Hello BartMan,

TriggerCustomEvent() must be used to synchronize series from a non-data-driven thread.
