EXPERIMENTAL: Experiment using Linear Regression based on %atr for decay(decay option is a mutiplier for the atr).
```study("[RS]Decay Channel Candles V0", overlay=true)
linreg_length = input(type=integer, defval=4)
atr_length = input(type=integer, defval=100)
decay = atr(atr_length)*input(type=float, defval=0.125)
prev_top = nz(top[1], high)-decay
prev_bot = nz(bot[1], low)+decay
abs_top = valuewhen(high >= prev_top, high, 0)
abs_bot = valuewhen(low <= prev_bot, low, 0)
top = high >= prev_top ? high : prev_top
bot = low <= prev_bot ? low : prev_bot
top_close = max(high, min(top, linreg(avg(top, high), linreg_length, 0)))
bot_close = min(low, max(bot, linreg(avg(bot, low), linreg_length, 0)))
//#9ce0b2//#e0b29c
top_palete = rising(abs(top-top_close),1)?orange:#e0b29c
bot_palete = rising(abs(bot-bot_close),1)?olive:#9ce0b2
plotbar(top,top,top,top_close, color=top_palete)
plotbar(bot,bot,bot,bot_close, color=bot_palete)
plot(abs_top, color=abs_top==abs_top[1]?maroon:na)
plot(abs_bot, color=abs_bot==abs_bot[1]?green:na)

```
Thanks for sharing,
I have quick question: how to draw lines ?

Draw_line(price1, candle1, price2, candle2)

how to achieve this function ?

Good indicator, for an Options trader. How and when to manage positions. Etc. Good job. Keep it flowing.......

it uses linear regression to map breakouts, on tight ranges you would need to accommodate the volume of decay manually to adjust to the tighter volatility(usually on accumulation zones but not limited as high volume volatility can result on the same effect), for clarification this is a lagging indicator and its purpose should be to give a better understanding of the underlying movement.
