Simulation or trade with real money?

First, you'd better spend some time optimizing the trading strategy for your needs and vision. Then run "flashback" command to check how successful your strategy would be on historical data. When you are ok with it, run real trading with dotrade or trade commands.

Try it in action

Run node app.js flashback data/btcusd2021.dat Simple btcusd 1 to simulate trading over btc/usd pair with Simple trading strategy over historical data.

Do real trading

• Get your account on HitBTC.
• Create api keys with Order book, History, Trading balance, Payment information and Place/cancel orders access rights.
• Pop it up with some usd
• Add .env file to the application root with content of:

HITBTC_API_KEY=xxxxx
HITBTC_SECRET_KEY=yyyyyy
HITBTC_MODE=market

• Run node app.js dotrade data/btcusd2021.dat Simple btcusd 1 to run trading.

Trade over few pairs based on settings.

No need to remember all symbol-strategies you are trading over. Edit traders array in settings/settings.js and run trading over them running node app.js trade. Use [up] and [down] keys for navigation between traders. Press [p] to pause traders loop for 30 seconds.

Important notes

• Be sure there's only one running instance trading on specific TradingSymbol/Strategy. App doesn't catch parallel instances and can't produce too much orders in this case.

Write your own trading strategy

• Extend Base class with other one and use its name instead of Simple when running the app.
• #todo: docs about getting statistics features from HistoricalMarketPriceCombined

Want to try other pairs?

• Donwload .csv file with historical prices from Kaggle here.
• Compress .csv file to binary format for faster reading: node app.js cachecsv path/to/file.csv
• Or compress part of .csv file for faster reading of final .dat file: node app.js cachecsv path/to/file.csv maxWeeksCount startTimestamp
• Check compressed .dat file: node app.js testdat path/to/file.dat
• Be sure this trading pair is available on HitBTC, check pairs here. Use symbol as pairsymbol when running the app.
• Try running trading simulation over it: node app.js flashback path/to/file.dat Simple pairsymbol 1
