EXAMPLES

Below is a sample program which shows basic usage of the library.

// file index.js
(async function () {
  try {
    const PanicCloseStrategy = require('./strategy.js');
    await PanicCloseStrategy.start()
  } catch (err) {
    console.error('err', err)
  }
})()

// file strategy.js
global.log = global.log || console.log 
global.error = global.error || console.error

// never use console in your program, it doesn't exists in the isolated environment, use global.log in order to receive logs in your account dashboard
module.exports = class extends (global.Trader || require('jsmex-trader-sdk')) {
  constructor (options) {
    super(options)
    this.defaultSymbol = this.options.defaultSymbol
  }

  /**
     * SamplePanicCloseStrategy on init method
     *
     * @author jsb4ch <[email protected]>
     * @since 1.1.0
    */
  onInit () {

  }

  /**
     * SamplePanicCloseStrategy on tick method
     *
     * @author jsb4ch <[email protected]>
     * @since 1.1.0
    */
  async onTick () {
    try {
      let close = this.close()
      let yesterdayOpen = this.open(24)
      let rate = (
        close.minus(yesterdayOpen)
      ).div(yesterdayOpen)
      if (rate.lte(-0.2)) {
        return this.cancelAllOrders()
      } else {
        global.log(rate.toNumber())
      }
    } catch (err) {
      global.error(err)
    }
  }

  /**

  onExit () {

  }

  /**
