a text parser that will attempt to export a text encoded composer symphony, to whatever text endpoint you want
- human readable output
- vectorbt (WIP)
- quantconnect
- tradingview
- thinkscript
Use python3.
pip3 install -r requirements.txtpython3 parser.py -i infile -o outfile -m quantconnect saves quantconnect parsed output to "outfile"
python3 ./parser.py -i inputs/simple.edn -m vector prints vectorbt output to screen
python3 parser.py -i infile will just print human readable output to the screen
python3 ./parser.py -m vector -i https://app.composer.trade/symphony/PdgUAAy4GmEQvGyKsYZt/details -u will print a vectorbt formatted output, will download a symphony directly from composer
python3 ./parser.py -m human -u -i https://app.composer.trade/symphony/PdgUAAy4GmEQvGyKsYZt/details -p prints a human formatted output, download the json formatted edn_encoded symphony directly from composer, AND all symphony parents, printing them directly to the screen
python3 ./parser.py -m human -p -u -b -i inputs/bulk_symphonies.txt prints a human formatted output, download the json formatted edn_encoded symphony directly from composer, all symphony parents, printing them directly to the screen, AND reads the text file which contains a list of urls which it bulk reads from. can be urls or a list of local file paths for json encoded edn files.
infile: the file that contains the text encoded symphony
you can now use the -u option when specifying an infile. This will cause it to treat the infile as a symphony url and it will then pull the data down from composer.
outfile: the file you want the parsed output to go to quantconnect: the output mode style eventual, hopeful, supported output style modes: quantconnect, vectorbt, tradingview, thinkscript
in order for an output style to be supported, it does not have to be 100% complete. it can only be 10% complete to be supported. as long as it helps someone convert the original text, and get them closer from the original encoded text, to the "Other" system, then its a nice, good conversion.
to get the backtesting syntax:
"in your composer page, before you change a date on the backtesting graph, and cause the webpage to do another backtest, have the inspect tool open, and on the network tab, so it's monitoring your network traffic. change the date. this will send a request to the backend. as it's monitoring your networking graph, it will endcode the symphony on the page in text, and you should be able to find it in one of those."
