Could someone convert Wave-PM from TradingView?

[superfatkorean]

The indicator is Wave-pm and I honestly think its the best volatility indicator there is. If someone could help me translate this into think script It would be awesome .

study("Wave-PM")

fastPeriod = input(14, "Fast Period", input.integer, minval=5, maxval=1000)
slowPeriod = input(55, "Slow Period", input.integer, minval=5, maxval=1000)
slowerPeriod = input(100, "Slow Period", input.integer, minval=5, maxval=1000)
multiplier = input(2.2, "Stddev Multiplier", input.float, minval=1, maxval=5)

wpm(length) =>
    dev = multiplier * stdev(close, round(length))
    dev1 = pow(dev / syminfo.pointvalue, 2)
    temp = sqrt(sma(dev1, 100)) * syminfo.pointvalue
    temp := temp != 0  ? dev/temp : temp
    return = if temp > 0
        iexp = exp(-2*temp)
        (1-iexp)/(1+iexp)
    else
        iexp = exp(2*temp)
        (iexp-1)/(1+iexp)

val1 = wpm(fastPeriod)
val2 = wpm(slowPeriod)
val3 = wpm(slowerPeriod)


plot(val1, title="Fast", color=color.red, style=plot.style_line, linewidth=2)
plot(val2, title="Slow", color=color.blue, style=plot.style_line, linewidth=2)
plot(val3, title="Slower", color=color.yellow, style=plot.style_line, linewidth=2)


hline(0.9, title="Danger", color=color.red, linestyle=hline.style_dotted)
hline(0.7, title="Breakout", color=color.red, linestyle=hline.style_dotted)
hline(0.5, title="Consolidation", color=color.red, linestyle=hline.style_dotted)
hline(0.35, title="Gear Change", color=color.red, linestyle=hline.style_dotted)

I came across wave-pm from crypto traders but never seen it used on stocks. Originally made for forex by mark whistler. The indicator aims to detect the weight of the pairs trading. Its like a rsi with no directional signal rather a prediction of volatility . I plan to use this on tos so I can scan penny stocks since I think this indicator does exceptionally well. The only problem being the window of entry being very short.

I hope someone can help converting this, would like to try it.

im converting it rn. The built in functions on tos is different than trading view so it might take sum time :C.

Wave-pm is basically a normalized version of bollinger band width. So if you just want to scan you can just use bbw crosses.
