Convert from Tradingview to PRT

Hello, I have a code in tradingview that I have tried to convert to PRT but I struggeling. The code in Tradingview is: I dont need the plot shapes and so on just the indicator. src = input(defval=close, title=’Source’) per = input.int(defval=100, minval=1, title=’Sampling Period’) mult = input.float(defval=3.0, minval=0.1, title=’Range Multiplier’) smoothrng(x, t, m) => wper = t * 2 – 1 avrng = ta.ema(math.abs(x – x[1]), t) smoothrng = ta.ema(avrng, wper) * m smoothrng smrng = smoothrng(src, per, mult) rngfilt(x, r) => rngfilt = x rngfilt := x > nz(rngfilt[1]) ? x – r nz(rngfilt[1]) ? nz(rngfilt[1]) : x + r rngfilt filt = rngfilt(src, smrng) upward = 0.0 upward := filt > filt[1] ? nz(upward[1]) + 1 : filt filt[1] ? 0 : nz(downward[1]) hband = filt + smrng lband = filt – smrng filtcolor = upward > 0 ? color.lime : downward > 0 ? color.red : color.orange barcolor = src > filt and src > src[1] and upward > 0 ? color.lime : src > filt and src 0 ? color.green : src 0 ? color.red : src src[1] and downward > 0 ? color.maroon : color.orange filtplot = plot(filt, color=filtcolor, linewidth=3, title=’Range Filter’) hbandplot = plot(hband, color=color.new(color.aqua, 100), title=’High Target’) lbandplot = plot(lband, color=color.new(color.fuchsia, 100), title=’Low Target’) fill(hbandplot, filtplot, color=color.new(color.aqua, 90), title=’High Target Range’) fill(lbandplot, filtplot, color=color.new(color.fuchsia, 90), title=’Low Target Range’) barcolor(barcolor) longCond = bool(na) shortCond = bool(na) longCond := src > filt and src > src[1] and upward > 0 or src > filt and src 0 shortCond := src 0 or src src[1] and downward > 0 CondIni = 0 CondIni := longCond ? 1 : shortCond ? -1 : CondIni[1] longCondition = longCond and CondIni[1] == -1 shortCondition = shortCond and CondIni[1] == 1 plotshape(longCondition, title=’Buy Signal’, text=’LONG’, textcolor=color.new(color.white, 0), style=shape.labelup, size=size.normal, location=location.belowbar, color=color.new(color.green, 0)) plotshape(shortCondition, title=’Sell Signal’, text=’SHORT’, textcolor=color.new(color.white, 0), style=shape.labeldown, size=size.normal, location=location.abovebar, color=color.new(color.red, 0)) alertcondition(longCondition, title=’Buy Alert’, message=’BUY’) alertcondition(longCondition, title=’Buy Alert’, message=’BUY’) alertcondition(longCondition, title=’Buy Alert’, message=’BUY’) alertcondition(shortCondition, title=’Sell Alert’, message=’SELL’)

Hello,
I have a code in tradingview that I have tried to convert to PRT but I struggeling.

The code in Tradingview is:

I dont need the plot shapes and so on just the indicator.

src = input(defval=close, title=’Source’)

per = input.int(defval=100, minval=1, title=’Sampling Period’)

mult = input.float(defval=3.0, minval=0.1, title=’Range Multiplier’)

smoothrng(x, t, m) =>

wper = t * 2 – 1

avrng = ta.ema(math.abs(x – x[1]), t)

smoothrng = ta.ema(avrng, wper) * m

smoothrng

smrng = smoothrng(src, per, mult)

rngfilt(x, r) =>

rngfilt = x

rngfilt := x > nz(rngfilt[1]) ? x – r < nz(rngfilt[1]) ? nz(rngfilt[1]) : x – r : x + r > nz(rngfilt[1]) ? nz(rngfilt[1]) : x + r

rngfilt

filt = rngfilt(src, smrng)

upward = 0.0

upward := filt > filt[1] ? nz(upward[1]) + 1 : filt < filt[1] ? 0 : nz(upward[1])

downward = 0.0

downward := filt < filt[1] ? nz(downward[1]) + 1 : filt > filt[1] ? 0 : nz(downward[1])

hband = filt + smrng

lband = filt – smrng

filtcolor = upward > 0 ? color.lime : downward > 0 ? color.red : color.orange

barcolor = src > filt and src > src[1] and upward > 0 ? color.lime : src > filt and src < src[1] and upward > 0 ? color.green : src < filt and src < src[1] and downward > 0 ? color.red : src < filt and src > src[1] and downward > 0 ? color.maroon : color.orange

filtplot = plot(filt, color=filtcolor, linewidth=3, title=’Range Filter’)

hbandplot = plot(hband, color=color.new(color.aqua, 100), title=’High Target’)

lbandplot = plot(lband, color=color.new(color.fuchsia, 100), title=’Low Target’)

fill(hbandplot, filtplot, color=color.new(color.aqua, 90), title=’High Target Range’)

fill(lbandplot, filtplot, color=color.new(color.fuchsia, 90), title=’Low Target Range’)

barcolor(barcolor)

longCond = bool(na)

shortCond = bool(na)

longCond := src > filt and src > src[1] and upward > 0 or src > filt and src < src[1] and upward > 0

shortCond := src < filt and src < src[1] and downward > 0 or src < filt and src > src[1] and downward > 0

CondIni = 0

CondIni := longCond ? 1 : shortCond ? -1 : CondIni[1]

longCondition = longCond and CondIni[1] == -1

shortCondition = shortCond and CondIni[1] == 1

plotshape(longCondition, title=’Buy Signal’, text=’LONG’, textcolor=color.new(color.white, 0), style=shape.labelup, size=size.normal, location=location.belowbar, color=color.new(color.green, 0))

plotshape(shortCondition, title=’Sell Signal’, text=’SHORT’, textcolor=color.new(color.white, 0), style=shape.labeldown, size=size.normal, location=location.abovebar, color=color.new(color.red, 0))

alertcondition(longCondition, title=’Buy Alert’, message=’BUY’)

alertcondition(longCondition, title=’Buy Alert’, message=’BUY’)

alertcondition(longCondition, title=’Buy Alert’, message=’BUY’)

alertcondition(shortCondition, title=’Sell Alert’, message=’SELL’)

As far I have tried:

indicator(title=’LONG SHORT ASR’, overlay=true)

src = input(defval=close, title=’Source’)

per = input.int(defval=100, minval=1, title=’Sampling Period’)

mult = input.float(defval=3.0, minval=0.1, title=’Range Multiplier’)

src = close

perioddefault = 100

periodminvalue = 1

mult = 3.0

multmin = 0.1

smoothrng = Abs(x / t / m)

wper = t * 2 – 1

avrng = exponensial.average(abs(x – x[1]), t)

smoothrng = exponensial.average(avrng, wper) * m

smoothrng

smrng = smoothrng(src / per / mult)

rngfilt = abs(x / r) =>

rngfilt abs(x / r) =

float filt = x

prevFilt = nz(rngfilt[1])

if x > prevFilt then

filt = min(x – r, prevFilt)

else

filt = max(x + r, prevFilt)

endif

filt = rngfilt(src, smrng)

var float upward = 0.0

upward = iff(filt > filt[1], nz(upward[1]) + 1, iff(filt < filt[1], 0, nz(upward[1])))

downward = 0.0

downward = iff(filt < filt[1], nz(downward[1]) + 1, iff(filt > filt[1], 0, nz(downward[1])))

hband = filt + smrng

lband = filt – smrng

boolean longCond = false

boolean shortCond = false

longCond = (src > filt and src > src[1] and upward > 0) or (src > filt and src < src[1] and upward > 0)

shortCond = (src < filt and src < src[1] and downward > 0) or (src < filt and src > src[1] and downward > 0)

CondIni = 0

CondIni = iff(longCond, 1, iff(shortCond, -1, CondIni[1]))

longCondition = longCond and CondIni[1] = -1

shortCondition = shortCond and CondIni[1] = 1

Hi @lukasmartens

This is the code of a “Range Filter”…

There is a “Twin Range Filter” in the library that gives the same results when you adjust the settings of the second filter…

Twin Range Filter
