This is a very simple binance trading bot which uses pandas-ta set of technical indicators from pandas-ta lib for tradinh.
Bot automatically fetches OHLCV data for TA models in SQLite database while it's working.
You can easily plug your strategy (instruction will be provided when it's ready)
You can download archive OHLCV data from Binance for free using this bot either for technical indicators usage by bot or just for your own needs.
I'm not sure if it's applicable to already delisted coins, but definitely works for coins that are currently listed on Binance.
Set BOT_PYTHON_DATABASE_UPDATE_START_RECORD to define epoch start point time
in the past.
For example, default timestamp value 1640995200000 which is 1st January 2022 00:00:00 and
bot will try to start fetch OHLCV data from this date up to today. Data granulation is
1 minute and bot fetches 720 minutes (12h) per single request and then it waits BOT_PYTHON_DATABASE_UPDATE_DELAY_SECS time
before the next request (Binance has API limits hence you should not try to download as fast as possible as they may block you)
Records which already exist in db just simply won't be added based on db schema and this is handled by SQLite itself - this there is no additional logic for that.
If you just want to use OHLCV for your own needs and tests, then you can use read_sql_query()
function from pandas as follow:
df = pd.DataFrame()
con = sqlite3.connect('btcusdt.db')
df = pd.read_sql_query("SELECT * from main.ohlcv_data ORDER BY open_time ASC", con)And in df dataframe you now have fetched OHLCV data for you own experiments, see more instruction
