Hello,

i am new to quantopian and i have some questions i didn't find answer to my question in quantopian's website.so i am approaching here please do asisst me to find the answers for these questions.

  1. Do i have to write the whole code of algorithm in a single file?

  2. Can we use database? I have my own strategy wchich enters and exits the trade according to the entry and exit signal which i store in a DB of my server. So is there a way to access my own server's Database through Quantopians code? I just checked The library modules supported by Quantopian i couldn't find 'MySQLdb' in the list.

Thanks

Hey, to answer your questions:

  1. Currently your algorithm is restricted to the single file that you may edit in the IDE.
  2. There is no way to read data out of an arbitrary database; however, you could write your signal to a hosted csv and then retrieve it with fetcher

Hopefully this helps.
