Need help !! I need to change the core indicator of bollinger bands to EMA

[Tarnawat Sonudom]

But i can't change to ema mode because I can't get the prev_value 

[Fabio Cavalloni]

Can you better specify what are you trying to do?

[Tarnawat Sonudom]

I need to change from SimpleMa to ExponentialMA

[Conor Mcnamara]

You should use an EMA function to replace the MA.
