  Buongiorno a tutti,

  vorrei provare questo interessante codice trovato su TW, abbastanza recente e che mi sembra interessante.

  Un grande grazie per il consueto aiuto.

  https://www.tradingview.com/script/T7AZI0z6-Trend-Reversal-Predictor/

  //@version=5
  indicator(“Danger Zones”, overlay=true)

  // Step 1: Trend Identification
  length = input.int(200, minval=1)
  src = input(close, title=”Source”)
  hma = ta.wma(2 * ta.wma(src, length / 2) – ta.wma(src, length), math.floor(math.sqrt(length)))
  start = input(0.02)
  increment = input(0.02)
  maximum = input(0.2, “Max Value”)
  sar = ta.sar(start, increment, maximum)

  trendUp = close > hma and close > sar
  trendDown = close < hma and close < sar
  trendNeutral = not trendUp and not trendDown

  // Step 2: Danger Zone Identification
  buyingVolumeSlowdownPeriod = input(5, title=”Buying Volume Slowdown Period”)
  sellingVolumeSlowdownPeriod = input(5, title=”Selling Volume Slowdown Period”)
  buyingVolumeRateOfChange = ta.change(volume, buyingVolumeSlowdownPeriod)
  sellingVolumeRateOfChange = ta.change(volume, sellingVolumeSlowdownPeriod)
  adrPeriod = input(14, title=”Average Daily Range (ADR) Period”)
  adr = ta.atr(adrPeriod)

  // Calculate average volume rate of change and net price movement
  averageBuyingVolumeRateOfChange = ta.sma(buyingVolumeRateOfChange, 5)
  averageSellingVolumeRateOfChange = ta.sma(sellingVolumeRateOfChange, 5)
  averageNetPriceMovement = ta.sma(close – close[1], 5)

  // RSI Integration
  ma(source, length, type) =>
  switch type
  “SMA” => ta.sma(source, length)
  “Bollinger Bands” => ta.sma(source, length)
  “EMA” => ta.ema(source, length)
  “SMMA (RMA)” => ta.rma(source, length)
  “WMA” => ta.wma(source, length)
  “VWMA” => ta.vwma(source, length)

  rsiLengthInput = input.int(14, minval=1, title=”RSI Length”, group=”RSI Settings”)
  rsiSourceInput = input.source(close, “Source”, group=”RSI Settings”)
  maTypeInput = input.string(“SMA”, title=”MA Type”, options=[“SMA”, “Bollinger Bands”, “EMA”, “SMMA (RMA)”, “WMA”, “VWMA”], group=”MA Settings”)
  maLengthInput = input.int(14, title=”MA Length”, group=”MA Settings”)
  bbMultInput = input.float(2.0, minval=0.001, maxval=50, title=”BB StdDev”, group=”MA Settings”)

  up = ta.rma(math.max(ta.change(rsiSourceInput), 0), rsiLengthInput)
  down = ta.rma(-math.min(ta.change(rsiSourceInput), 0), rsiLengthInput)
  rsi = down == 0 ? 100 : up == 0 ? 0 : 100 – (100 / (1 + up / down))
  rsiMA = ma(rsi, maLengthInput, maTypeInput)
  isBB = maTypeInput == “Bollinger Bands”
  rsiBelowMA = rsi < rsiMA
  rsiAboveMA = rsi > rsiMA

  // Step 3: Trend Ending Prediction

  // Combine Conditions
  uptrendDangerZone = trendUp and buyingVolumeRateOfChange <= averageBuyingVolumeRateOfChange and averageNetPriceMovement < 0 and rsiBelowMA
  downtrendDangerZone = trendDown and sellingVolumeRateOfChange <= averageSellingVolumeRateOfChange and averageNetPriceMovement > 0 and rsiAboveMA
  rsiConditionUp = trendUp and rsiBelowMA
  rsiConditionDown = trendDown and rsiAboveMA
  trendReversalConditionUp = uptrendDangerZone and rsiConditionUp
  trendReversalConditionDown = downtrendDangerZone and rsiConditionDown

  // Final Trend Ending Prediction
  trendEndingPredictionUp = trendReversalConditionUp and rsiBelowMA
  trendEndingPredictionDown = trendReversalConditionDown and rsiAboveMA

  bgcolor(uptrendDangerZone ? color.orange : downtrendDangerZone ? color.blue : na, transp=70)
