I took a look at your $20 offer, I think what you ask is mostly impossible, since one cannot dynamically look up sids based on symbols.

That works in the IDE, but if you are getting symbols from a CSV file you fetch, I am 90% sure you cannot then turn around and use the symbol function to get the sid for them. You should try it out, the $20 could be yours!

Not interested in the 20$ but do you really need the sid since you can do something like:
sym = 'XXX' #load from CSV
context.sec1 = symbol(sym)

Or maybe I'm missing something!!?

Yeah I am pretty sure that won't work if the symbols are in the CSV. However, as I said, one could probably just run a sweeping fundamentals query, then just do something like df = df[df.symbol.isin(csv_symbols)] and then update_universe with that.

EDIT: whoops I see now I didn't say that, so this is the first time. Going senile.

hey guys thanks for your input.
i got a freelancer to do it for 500 dollars in one week. i was hoping someone would have done it before, that would pass his code to me for a couple of 10s of dollars.
i am still learning Quantopian, cant even assess whether it s feasible, but the dude, who apparently has a large experience here guaranteed it can be done.
my code is working using python, i just needed a 3rd party confirmation as a first step here. then later i may opt for more.
thanks again, i ll try your hints.

I did something similar a while back, you have the pre-code all possible symbols you are going to use with a max of 200 symbols. Since Q does't support dynamic symbol allocation, but it is straightforward.
There is also a small problem in the specification that you will find out when you go live.

hey look what i found here, the dude dude made 90% of the task! :D

Yeah, that's if you pre-populate all the possible symbols in the algo to start with, as Lucas said.

Hmm that's interesting you write it does not even build something like:

sym = "AMGN"  
context.sec3 = symbol(sym)  

So you can't load any symbol at run time...Any reason why was not built that way!!?
