Cryptocurrency Trading Bot

I'm using this bot for a long time now and wanted to share it.

Feel free to make it your own. PRs are welcome!

USE AT YOUR OWN RISK

A trading bot that does what you order him to do (use at your own risk)

I'm not responsible for anything

EMA crossover strategy

It's using the ema crossover strategy. But instead of EMA 5 and EMA 20 I'm using EMA 9 and EMA 26

Program Sequence

Main loop

  start = async () => {
    const start = now();
    log.info(`########## Started ichimoku ##########`);

    await this.collectRevenue();

    const markets: Market[] = await this.getMarkets();
    const marketSummaries: MarketSummary[] = await this.getMarketSummaries(
      markets
    );
    await this.evaluateMarkets(marketSummaries.map(({ symbol }) => symbol));

    // await this.report();

    log.info(`########## Finished ${(now() - start).toFixed(5)} ms ##########`);
  };

Collecting Revenue

    await this.collectRevenue();

• Fetch you current balances
  • Only checks assets where available coins are greater than 0
  • Ignore assets that you want to HODL see config
• Iterate over every balance
  • Fetch current market ticker for this balance (e.g. ETH-USDT)
  • Calculates how much revenue is already earned (current value minus invest)
  • When greate than invest try to sell that bit
    • e.g. Current value 57 USDT with an invest of 50 USDT -> sell 7 USDT worth
    • It can only sell when the quantity will be greater than the minimum trade size allowed by bittrex

Evaluate Markets

    const markets: Market[] = await this.getMarkets();
    const marketSummaries: MarketSummary[] = await this.getMarketSummaries(
      markets
    );
    await this.evaluateMarkets(marketSummaries.map(({ symbol }) => symbol));

• Filter the markets getMarkets and getMarketSummaries
  • Only use markets using the config.mainMarket here USDT
  • Only use market which are ONLINE
  • Check against market summary to see if the quote volume is greater than 0 (market is being traded on)
• Use those filtered marked for the next step -> evaluateMarkets
• Iterate over every market
  • Ignore HODL markets (just buy some manually and HODL on)
  • Get candles
  • Count EMA ticks. Positive and negative
  • If you got some of that asset in your balance
    • If it's on the blacklist it will sell it. E.g. Bittrex delisting coins
    • If it got too many negative ticks it will sell it
  • If you don't have any of that asset in you balance
    • If it's not blacklisted and got the amount of positiv ticks it will buy

Selling: It will be a limit sell with timeInForce: TimeInForce.FILL_OR_KILL Meaning, either it gets sold directly or the order gets canceled and will be tried next round.

Buying: The positiv ticks need to be exact the value defined in the config. This will prevent buying into a market "too late"

(optional) Report

    // await this.report();

Enable this line to report your current state. You will also need to enter your url in api/BittrexApi.ts report()

This could be used to track your bot and how much your balances are worth over time.
