  • redis database (redis cli)
  • bithumb price, volume crawler
  • tracker (selector > ohlcBuilder> analyzer)
  • botManager (to change configuration via slack)

Workspace Operation

redis operation

• memory database cotains crawled cryptocurrency information by crawler.js
• selector.js will access this database peridically

start

/etc/init.d/redis-server start

stop

/etc/init.d/redis-server stop

restart

/etc/init.d/redis-server restart

StockChart Operation

• render chart from csv file (chart/public/chart.js) to ide.c9.io url

start

cd ~/workspace/chart/
npm start &

Analyzing Files Explanation

selector.js

• read cryptocurrency data peridically

ohlcBuilder.js

• calculate OHLC by chunking array pushed by selector.js

chartFeeder.js

• feed OHLC data in csv format to /chart/chart.js

chart/src/chart.js

• invoked by updating chart/public/CandleData.csv
• render stock candle and MACD chart to ide.c9.io screen

analyzer.js

• calculate MACD, signal, histogram
• analyze buy,sell time using histogram (= divergence)
• inform thru notifier.js whether to buy,sell

notifier.js

• send various message to slack bia webhook

Minor Files

coinInfo.js

• create one by one transaction provided by crawler.js

notiType.js
