  Hi everyone,

  Wondered if anyone would be able to help convert this NinjaTrader code for an indicator into Prorealcode?

  const predef = require('./tools/predef') class tikiScalper { init() { this.isBuy = true } map(d, i, history) { if (i < 5) { return } const close = d.close() const priorClose = history.get(i - 1).close() const priorPriorClose = history.get(i - 2).close() const priorPriorPriorClose = history.get(i - 3).close() const isBuy = priorClose < close && (priorPriorClose < priorClose || priorPriorPriorClose < priorClose) const isSell = priorClose > close && (priorPriorClose > priorClose || priorPriorPriorClose > priorClose) if (isBuy) { this.isBuy = true } else if (isSell) { this.isBuy = false } const { upColor, downColor } = this.props const color = this.isBuy ? upColor: downColor return { candlestick: { color } } } } module.exports = { name: 'tikiScalper', description: 'Tiki Scalper', calculator: tikiScalper, params: { upColor: predef.paramSpecs.color('lime'), downColor: predef.paramSpecs.color('red'), }, tags: ['Tiki Tools'] }

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56

  const predef = require('./tools/predef')   class tikiScalper {     init() {         this.isBuy = true     }       map(d, i, history) {         if (i < 5) {             return         }                  const close = d.close()         const priorClose = history.get(i - 1).close()         const priorPriorClose = history.get(i - 2).close()         const priorPriorPriorClose = history.get(i - 3).close()                  const isBuy = priorClose < close &&             (priorPriorClose < priorClose ||             priorPriorPriorClose < priorClose)                  const isSell = priorClose > close &&             (priorPriorClose > priorClose ||             priorPriorPriorClose > priorClose)                      if (isBuy) {             this.isBuy = true         } else if (isSell) {             this.isBuy = false         }                  const {             upColor,             downColor         } = this.props                  const color = this.isBuy ? upColor: downColor                  return {             candlestick: {               color             }         }     } }   module.exports = {     name: 'tikiScalper',     description: 'Tiki Scalper',     calculator: tikiScalper,     params: {         upColor: predef.paramSpecs.color('lime'),         downColor: predef.paramSpecs.color('red'),     },     tags: ['Tiki Tools'] }

  Many thanks,

  Hi,

  Hereby the conversion:

  Tiki Scalper

  Once isBuy=1 If BarIndex>5 then PClose=Close[1] PPClose=Close[2] PPPClose=Close[3] isBuy=(PClose<Close) and ((PPClose<PClose) or (PPPClose<PClose)) isSell=(PClose>Close) and ((PPClose>PClose) or (PPPClose>PClose)) EndIf If isBuy then isBuy=1 ElsIf isSell then isBuy=0 EndIf If isBuy=1 then DrawCandle(Open,High,Low,Close)Coloured("Lime") Else DrawCandle(Open,High,Low,Close)Coloured("Red") EndIf Return

  1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24

  Once isBuy=1   If BarIndex>5 then PClose=Close[1] PPClose=Close[2] PPPClose=Close[3]   isBuy=(PClose<Close) and ((PPClose<PClose) or (PPPClose<PClose)) isSell=(PClose>Close) and ((PPClose>PClose) or (PPPClose>PClose)) EndIf   If isBuy then isBuy=1 ElsIf isSell then isBuy=0 EndIf   If isBuy=1 then DrawCandle(Open,High,Low,Close)Coloured("Lime") Else DrawCandle(Open,High,Low,Close)Coloured("Red") EndIf   Return
