  Salut à tous ;

  Y aurait-il des personnes sachant traduire les codes  tradovate/ninja en Pro real time ?

  C’est une TIKI cumulative delta.

   

  Merci à vous

   

  const predef = require(“./tools/predef”);
  const meta = require(“./tools/meta”);

  function number(defValue, step, min) {
  return {
  type: meta.ParamType.NUMBER,
  def: defValue,
  restrictions: {
  step: step || 1,
  min: min > 0 ? min : 0
  }
  };
  }

  class tikiCumulativeDeltaLine {
  init() {
  this.last = 0;
  this.tradeDate = 0;
  }

  map(d, i, history) {
  const bidVolume = d.bidVolume()
  const askVolume = d.offerVolume()
  const delta = askVolume – bidVolume

  const open = this.last;
  const close = open + delta;
  const range = Math.abs(open) > Math.abs(close) ? open : close;
  const prevd = i > 0 ? history.prior() : d;

  const type = this.props.type;
  const tradeDate = d.tradeDate();

  this.last = close;
  if (type === ‘chart’) {
  if (tradeDate !== this.tradeDate) {
  this.last = 0;
  this.tradeDate = tradeDate;
  }
  } else if (type === ‘session’) {
  const timestamp = d.timestamp();
  const hour = timestamp.getHours();
  const minute = timestamp.getMinutes();
  const startHour = this.props.startHour;
  const startMinute = this.props.startMinute;

  if (history.prior()) {
  const priorTimestamp = history.prior().timestamp();
  const priorHour = priorTimestamp.getHours();
  const priorMinute = priorTimestamp.getMinutes();

  // Hacky way to help tick charts work.
  const startTime = +(” + startHour + (startMinute < 10 ? ‘0’ : ”) + startMinute)
  const priorTime = +(” + priorHour + (priorMinute < 10 ? ‘0’ : ”) + priorMinute)
  const time = +(” + hour + (minute < 10 ? ‘0’ : ”) + minute)

  if (priorTime < startTime && time >= startTime) {
  this.last = 0;
  this.tradeDate = tradeDate;
  }
  }
  }
  return {
  delta: this.last,
  zero: 0
  }

  // return {
  // open,
  // close,
  // delta: this.last,
  // value: range
  // };
  }
  }

  module.exports = {
  name: “tikiCumulativeDeltaLine”,
  description: “Tiki Cumulative Delta Line”,
  calculator: tikiCumulativeDeltaLine,
  params: {
  type: predef.paramSpecs.enum({
  chart: ‘Chart’,
  session: ‘Session’
  }, ‘chart’),
  startHour: number(9, 1, 0),
  startMinute: number(30, 1, 0)
  },
  plots: {
  delta: { title: ‘Delta’ },
  zero: { title: ‘Zero’ }
  },
  inputType: meta.InputType.BARS,
  areaChoice: meta.AreaChoice.NEW,
  // plotter: predef.plotters.histogram,
  tags: [‘Tiki Tools’],
  schemeStyles: {
  dark: {
  delta: predef.styles.plot({
  color: “red”
  }),
  zero: predef.styles.plot({
  color: “yellow”
  })
  }
  }
  };
