Alert/Log entry from Indicator

[greg814]

Hello,

is there a way to create an alert when the input parameters of an indicator are set to illegal values. I would like to inform the user when changing them to legal ones.

This alert would have to be called only once but whether I put the alert statement in the Initialize() method or for the first bar into the OnBarUpdate() nothing seems to happen. Trying the same for a Log entry produces an actual error message.

Thanks for input..

Greg, the alert would only work in realtime on a fresh bar if triggered - I would just restrict the range of possible input values in the properties of the parameter.
