pivothigh(src, left, right, _id) {
        let id = this._tsid(_id, `pivothigh(${left},${right})`)

        let len = left + right + 1
        let top = src[right]
        for (var i = 0; i < len; i++) {
            if (top <= src[i] && i !== right) {
                return this.ts(NaN, id, src.__tf__)
            }
        }
        return this.ts(top, id, src.__tf__)
    }
Returns price of the pivot high point
Tip: works best with `offset` function
@param {TS} src - Input
@param {number} left - left threshold, candles
@param {number} right - right threshold, candles
@return {TS} - New time-series
