Add other filters this indicator(Standard Error Bands). Please.

[[Deleted]]

Hi. I'm Japanese. So I can't speak English. Sorry.

Many people uses there's own indicators.

I use "Standard Error Bands" indicator and BollingerBands.

Standard Error Bands show the direction of the current trend and the volatility around it.

Default settings are LinRegLength(21), SmoothingLength(3)

But I use LinRegLength(14), SmoothingLength(1) setting.

I made simple alert indicator. (I'm not programmer. It is poor)

It is sometimes show false signals.

Could you please help me add other filters this indicator?
