ふぉ

const pri = require('blac/lightning/builder/pub.js')
const moment = require('moment')

はっ

  function joinProduct (product_id) {
    return product_id.split('-')[0] + '_' + product_id.split('-')[1]
  }

ふぉっふぉ

    getTrades: function (opts, cb) {
      if (!pair) { pair = joinProduct(opts.product_id) }
      // Backfilling using the REST API
      if (opts.to || opts.to === null) {
        //var func_args = [].slice.call(arguments)

        if(!opts.from) {
          opts.from = 1
        }

        if(!opts.to) {
          opts.to = 999999999
        }

        body = new pri.getexecutions()
          .product_code(pair)
          .count(1000)
          .before(opts.to)
          .after(opts.from)

            size: trade.size,
            price: trade.price,
            side: trade.side == 'BUY' ? 'buy' : 'sell'

        cb(null, trades)

      } else {
        console.log("???")
      }

ほいっ

    getCursor: function (trade) {
      return (trade.trade_id || trade)
    }

まとめ
