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 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
NOTE: If SYM_LIST
is specified in user.json
, -f
or --sym
is not required unless you wish to override the default watchlist.
Identify chart patterns on a specific date.:
# iso date format YYYY-MM-DD
py init.py -f nifty_500.csv -d 2023-01-01
Save results as images to folder
# default folder is src/images
py init.py -f nifty_500.csv --save
# add a custom folder
py init.py -f nifty_500.csv --save ~/Desktop/pattern/
To skip the interactive prompt, specify a pattern string:
# Bullish VCP
py init.py -f nifty_500.csv -p vcpu
Pattern string can be one of:
Pattern String | Description |
---|---|
all | All patterns |
bull | All Bullish patterns |
bear | All Bearish patterns |
vcpu | VCP Up (Bullish) |
vcpd | VCP Down (Bearish) |
dbot | Double Bottom |
dtop | Double Top |
hnsu | Head & Shoulder Up (Bullish) |
hnsd | Head & Shoulder Down (Bearish) |
trng | Triangles (Symmetric, Ascending, Descending) |
There are other CLI options available for those wanting to tinker.
Key | Description |
---|---|
n | Next Chart |
p | Previous Chart |
NUM_KEY + j | Type the number followed by j to jump to index. Press ESC to clear |
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
py init.py --plot vcpu.json --idx 15
SAVE_STATE config option can be set in user.json. (See Configuration section below). It default to False.
Below behavior only applies, when set to True
.
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
By default, only the daily timeframe is scanned. You can specify the timeframe to scan with --tf
option.
Assume you have daily stock data.
py init.py --tf weekly
py init.py --tf monthly
If intraday data is configured, you can also scan intraday timeframes.
py init.py --tf 15
py init.py --tf 2h
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
user.json
is used for configuration and is auto-generated on first run.
Both absolute and relative file path are supported. Tilde or ~
for home directory symbol is also supported.
Parameter | Description |
---|---|
DATA_PATH | Required. Folder path for OHLC csv data. |
SYM_LIST | Optional. File path containing list of symbols, one per line. Override with -f or --file
|
SAVE_FOLDER | Optional. Folder path to save charts as images. Override with --save
|
POST_SCAN_PLOT | Default False. If True, plots the results on the chart after a scan. |
SAVE_STATE | Default False. If True, previously detected patterns will not be displayed in subsequent scans. |
LOADER | Optional. EODFileLoader (for daily) or IEODFileLoader for intraday data or any user-defined class |
DEFAULT_TF | Optional. Timeframe of OHLC file data stored in DATA_PATH. See below for details |
-
LOADER
can be eitherEODFileLoader
for daily and higher timeframes orIEODFileLoader
for intraday timeframes. -
EODFileLoader
uses daily as default timeframe. -
IEODFileLoader
uses 1min as the default timeframe. - If your data is stored in different timeframe, set the
DEFAULT_TF
accordingly. - If
--tf
is not used, the value ofDEFAULT_TF
or default timeframe of the Loader is used.
For IEODFileLoader
, valid values for DEFAULT_TF
are 1
, 5
, 10
, 15
, 25
, 30
, 60
, 75
, 125
, 2h
, 4h
.
For EODFileLoader
, valid values for DEFAULT_TF
are daily
, weekly
and monthly
