Usage

Display Help: py init.py -h

Show Version: py init.py -v

Scan stocks using a watchlist file. Pass a file containing stocks (one on each line).

# starts an interactive prompt
py init.py -f nifty_500.csv

See Chart controls on how to navigate charts.

Scan stocks from a list of symbols. Pass a list of symbols space separated.

py init.py --sym tcs astral datapattns

NOTES:

• If SYM_LIST is specified in config, -f or --sym is not required unless you wish to override the default watchlist.
• Starting with v4.0.10, if watchlist is missing and no symbols have been provided, all files in DATA_PATH folder will be scanned.

Identify chart patterns on a specific date.:

# iso date format YYYY-MM-DD
py init.py -d 2023-01-01

Save results as images to folder

# default folder is src/images
py init.py --save

# add a custom folder to save images
py init.py --save ~/Desktop/pattern/

To skip the interactive prompt, specify a pattern string:

# Bullish VCP
py init.py -p vcpu

Pattern string can be one of:

Pattern String	Description

** Does not include Trendlines, Triangle and Harmonic patterns.

Chart Plot options

Results of last scan, are saved as json files. Filename is same as pattern string, for E.g. vcpu.json

To plot results of scan, use --plot.

py init.py --plot vcpu.json

To jump to a particular count in the result, use --idx with a count you wish to jump to.

py init.py --plot vcpu.json --idx 15

SAVE_STATE config option

SAVE_STATE config option can be set in user.json. (See Configuration section below). Default is False.

When scanning using a watchlist file, all patterns are tracked in json files stored in src/state folder.

File format is <watchlist_name>_<pattern_name>.json. For e.g. nifty_500_vcpu.json.

Only newly detected patterns are notified and plotted on charts.

To see all currently active patterns in market, use the --plot passing the json file from state folder

py init.py --plot state/nifty_500_vcpu.json

Scanning other Timeframes

By default, only the daily timeframe is scanned. You can specify the timeframe to scan using --tf option.

Assume you have daily stock data.

py init.py --tf weekly

py init.py --tf monthly

py init.py --tf quarterly

If intraday data is configured, you can also scan intraday timeframes.

py init.py --tf 15

py init.py --tf 2h

Multiple config files

While user.json is the default config file. You can define additional config files. For ex. a config file for intraday data or different markets.

Use the -c or --config passing the path to JSON file.

py init.py -c intra_config.json
