any way the wave trend oscillator can be put in SC? this is code from Tradeovate.

const predef = require("./tools/predef");
const meta = require("./tools/meta");
const EMA = require("./tools/EMA");
const SMA = require("./tools/SMA");
const typicalPrice = require("./tools/typicalPrice");
const p = require("./tools/plotting");

class waveTrendOscillator {
init() {
this.c1 = EMA(this.props.channelLength);
this.c2 = EMA(this.props.channelLength);
this.a = EMA(this.props.averageLength);
this.s = SMA(this.props.smoothLength);

this.pWt1 = 0.0;
this.pWt2 = 0.0;

this.obIndex = 0;
this.osIndex = 0;

this.crossunderIndex = 0;
this.crossoverIndex = 0;
}

map(d, i, history) {
const typ = typicalPrice(d);

let esa = this.c1(typ);
let dist = this.c2(Math.abs(typ - esa));

let ci = (typ - esa) / (this.props.cciConstant * dist);
let ci2 = Number.isNaN(ci) ? 0 : ci

let wt1 = this.a(ci2);
let wt2 = this.s(wt1);

const obValue = Math.min(this.props.overbought1, this.props.overbought2)
const osValue = Math.max(this.props.oversold1, this.props.oversold2);

// save index of where ob/os condition occurred

if (this.pWt1 obValue) {
this.obIndex = i;
}

if (this.pWt1 >= osValue && wt1 < osValue) {
this.osIndex = i;
}

// crossunder from overbought

let sell = false;
let buy = false;

if (this.pWt1 >= this.pWt2 && wt1 < wt2) {
if (this.obIndex < i && this.obIndex > this.crossunderIndex) {
this.crossunderIndex = i;
sell = true;
}
}

// crossover from oversold

if (this.pWt1 wt2) {
if (this.osIndex < i && this.osIndex > this.crossoverIndex) {
this.crossoverIndex = i;
buy = true;
}
}

this.pWt1 = wt1;
this.pWt2 = wt2;

return {
waveTrend: wt1,
waveTrendSmooth: wt2,
ob1: this.props.overbought1,
ob2: this.props.overbought2,

os2: this.props.oversold2,

sellColor: this.props.sellColor,
}
}

filter(_, i) {
return i >= this.props.averageLength && i >= this.props.channelLength;
}
}

function tradePlotter(canvas, indicatorInstance, history) {
for(let i=0; i 0) {
if (item.buy || item.sell) {
const x = p.x.get(item);

const item1 = history.get(i - 1);
const x1 = p.x.get(item1);

const y = item.buy ? Math.min(item.waveTrend, item.waveTrendSmooth) : Math.max(item.waveTrend, item.waveTrendSmooth)

canvas.drawLine(
p.offset(x1, y),
p.offset(x, y),
{
color: item.buy ? item.buyColor : item.sellColor,
relativeWidth: 2,
opacity: 1.0
});
}
}

You might try directly reaching out to some of the people listed on the SC 3rd party page.

If you can accept this version, then I can do it. I do not have time to learn Tradeovate's proprietary language, but I know Tradingview's pretty well.

study(title="WaveTrend [LazyBear]", shorttitle="WT_LB")
n1 = input(10, "Channel Length")
n2 = input(21, "Average Length")
obLevel1 = input(60, "Over Bought Level 1")
obLevel2 = input(53, "Over Bought Level 2")
osLevel1 = input(-60, "Over Sold Level 1")
osLevel2 = input(-53, "Over Sold Level 2")

ap = hlc3
esa = ema(ap, n1)
d = ema(abs(ap - esa), n1)
ci = (ap - esa) / (0.015 * d)
tci = ema(ci, n2)

wt1 = tci
wt2 = sma(wt1,4)

plot(0, color=gray)
plot(obLevel1, color=red)
plot(osLevel1, color=green)
plot(obLevel2, color=red, style=3)
plot(osLevel2, color=green, style=3)

Thank you Tom,

I'd be willing to use it but not sure how to input your code into SC

I am still working on this. Normally, oscillators take on values from -100 to +100. But this one takes on very high values (due to the factor of 0.015 in the denominator of the Composite Index). I am trying to get to the bottom of this.

I just came across this thread as I was searching for the very same thing. Did the code get completed or is it still a work in progress?
