I made an strategy using Pinescript. Code is well started without error message. but plot of trailingstop line and barcolor function are not visible. I cannot understand why…

code is here:

//@version=5
strategy(title="UT Bot Strategy + STC", overlay = true)

// Inputs
a = input.float(1,     title = "Key Vaule. 'This changes the sensitivity'")
c = input(10,    title = "ATR Period")
h = input(false, title = "Signals from Heikin Ashi Candles")

xATR  = ta.atr(c)
nLoss = a * xATR

src = h ? request.security(ticker.heikinashi(syminfo.tickerid), timeframe.period, close, barmerge.gaps_off, barmerge.lookahead_off) : close

var float xATRTrailingStop = na
if src > nz(xATRTrailingStop[1],0) and src[1] > nz(xATRTrailingStop[1],0)
    xATRTrailingStop := math.max(xATRTrailingStop[1],src-nLoss)
else if src < nz(xATRTrailingStop[1],0) and src[1] < nz(xATRTrailingStop[1],0)
    xATRTrailingStop := math.min(xATRTrailingStop[1],src+nLoss)
else if src > xATRTrailingStop[1]
    src-nLoss
else
    src+nLoss
 
var color trailingstop_color = na
if close > xATRTrailingStop
    trailingstop_color:=color.red
else
    trailingstop_color:=color.green

plot(xATRTrailingStop,color=trailingstop_color,linewidth=2)

ema   = ta.ema(src,1)
above = ta.crossover(ema, xATRTrailingStop)
below = ta.crossover(xATRTrailingStop, ema)

buy  = src > xATRTrailingStop and above 
sell = src < xATRTrailingStop and below

barbuy  = src > xATRTrailingStop 
barsell = src < xATRTrailingStop 

plotshape(buy,  title = "Buy",  text = 'Buy',  style = shape.labelup,   location = location.belowbar, color= color.green, textcolor=color.white, size = size.tiny)
plotshape(sell, title = "Sell", text = 'Sell', style = shape.labeldown, location = location.abovebar, color= color.red,   textcolor = color.white, size = size.tiny)

barcolor(barbuy  ? color.green : na)
barcolor(barsell ? color.red   : na)



EEEEEE = input(12, 'Length')
BBBB = input(26, 'FastLength')
BBBBB = input(50, 'SlowLength')

AAAA(BBB, BBBB, BBBBB) =>
    fastMA = ta.ema(BBB, BBBB)
    slowMA = ta.ema(BBB, BBBBB)
    AAAA = fastMA - slowMA
    AAAA

AAAAA(EEEEEE, BBBB, BBBBB) =>
    AAA = input(0.5)
    var CCCCC = 0.0
    var DDD = 0.0
    var DDDDDD = 0.0
    var EEEEE = 0.0
    BBBBBB = AAAA(close, BBBB, BBBBB) 
    CCC = ta.lowest(BBBBBB, EEEEEE) 
    CCCC = ta.highest(BBBBBB, EEEEEE) - CCC 
    CCCCC := CCCC > 0 ? (BBBBBB - CCC) / CCCC * 100 : nz(CCCCC[1]) 
    DDD := na(DDD[1]) ? CCCCC : DDD[1] + AAA * (CCCCC - DDD[1]) 
    DDDD = ta.lowest(DDD, EEEEEE)
    DDDDD = ta.highest(DDD, EEEEEE) - DDDD
    DDDDDD := DDDDD > 0 ? (DDD - DDDD) / DDDDD * 100 : nz(DDDDDD[1])
    EEEEE := na(EEEEE[1]) ? DDDDDD : EEEEE[1] + AAA * (DDDDDD - EEEEE[1])
    EEEEE


mAAAAA = AAAAA(EEEEEE, BBBB, BBBBB)


if buy and mAAAAA <=25
    strategy.entry("Long",strategy.long,10)
else if mAAAAA >= 75
    strategy.close("Long")
else if close <= strategy.opentrades.entry_price(strategy.opentrades-1)-nLoss
    strategy.close("Long")


if sell and mAAAAA >= 75
    strategy.entry("Short",strategy.short,10)
else if mAAAAA <= 25
    strategy.close("Short")
else if close >= strategy.opentrades.entry_price(strategy.opentrades-1)+nLoss
    strategy.close("Short")

This strategy consists of two parts: breakout of trailingstop(finding strong trend) and oscillator(for filtering).

Can you help me? 🙂

If you found correct code, then let me know.
