I wanted to create a new custom indicator called GannFanTest2, so
I opened up an existing indicator (I randomly chose the RegressionChannel indicator), and stripped out basically all the code and wrote in my simple changes (I've attached the new CS file here).
Now since the new indicator didn't require any properties, I commented out the one property that had been defined in the RegressionChannel code. The name of that property was "Period".
Now, when I compile the new indicator, it errors out, because the NinjaScript code that has been automatically added to the indicator is still looking for that old property "Period" to be defined. I believe this was also a problem under v6.5.
