ROC - Rate Of Change Strategy (Help!)

[fcl]

Hello! I would like to run a simple strategy based ROC.

I'm using the ui Gekko and already have the indicator installed (.../gekko-stable/gekko-stable/strategies/ROC.js)
But when I select ROC on the drop down menu, the parameters are empty.
For example: when I select RSI, the RSI default parameters are:

"interval = 14

[thresholds]
low = 30
high = 70
persistence = 1"

Someone know what would be the necessary parameters for ROC?

Thank you!!
