@dpguoming sorry for the delay. Would you mind fixing the lint issues?

Hi guys,

Just a quick question. I tried to use pyserum to automate some trades but the queries are very slow (especially to get open orders). I used my own private rpc and it still took some time to interact with serum (up to 15 sec) where with solana the interaction are way quicker.

I was wondering if the problem came from the layer added by pyserum or is serum slow by nature?

Thanks for your time

Querying Serum data is slow. Try talk to your RPC Provider and see if there are able to optimize the query time. adrida ***@***.***> 于2022年6月27日周一 05:01写道：

I understand, thanks a lot! Maybe there is a way to bypass serum and talk directly to the smart contract? Can people really do automated trading on serum markets with dozens of seconds in delay to get the data?

I tried a few times to pass CI, but it might be some different between auto-execute with my environment. Would you mind to assist it, I have opened the permission.
