Ehlers Adaptive Commodity Channel Index V1 [CC]

The Adaptive Commodity Channel Index V1 was created by John Ehlers (Rocket Science For Traders pgs 236-237) and this is the typical Commodity Channel formula with the introduction of adaptive lengths based on his earlier work with indicators such as the Mother of Adaptive Moving Averages. For longer term signals you would get a bullish signal when CCI is above 0 and a bearish signal when CCI falls below 0. For shorter term signals you would get a bullish signal when crosses over it's overbought level or when it crosses above it's oversold level or vice versa. I have included both signals to make it easier.

Hi @cheatcountry , is it a bug, the scale it shown 0 to (near stock price range) on my pane, instead of -200 to 200 ?

@cheatcountry, You have the buy/sell plotshapes plotting above/below bar. It looks fine within the $200 price range in your screenshot. If used on a instrument with a higher price like BTC, the oscillator looks squished because it is centered on 0 but the plotshapes are plotting around the 12000 price range.

I just went through the script, some comments as below:

1. "period := im != 0 and re != 0 ? 360 / atan(im / re) : 0" , I understand "360 " here should be changed into "2*pi".

2. "period := im != 0 and re != 0 ? 360 / atan(im / re) : 0
period := min(max(period, 0.67 * nz(period)), 1.5 * nz(period))
period := min(max(period, 6), 50)
period := (0.2 * period) + (0.8 * nz(period))" , the order of 'period' assignment, i remember "min 1.5 * nz(period)" should be first handled. However, i am not sure whether it will contribute to different results or not.

3. "length = ceil(cycPart * smoothPeriod)", 'ceil' function here should be 'round', but when i changed it, pine reported an error of nagtive value. I have no idea why this happen.

could you look into them and check whether they are valid or not? thanks in advance!
thanks for sharing this, really appreciate :D
