For instance, can a bot created using Quantconnect's platform have some 200 stocks in its universe and react accurately on second-level resolution (say for each ticker it has to keep track of several different indicators, and go through conditional logic for entries, taking profits, and stops)? What about 10 second? If I am interested in faster runtimes, would using Interactive Broker's native TWS library run any faster? Would a different broker or platform be a better choice? I've been looking around the Discussions but it seems most people use Quantconnect for swing trading/investing, or if day trading only look at several tickers say on minute-level resolution.

Hi Dahui,
200 assets @ the second level would be fine, C# would be safest. It would likely be a 100ms delay during peak times (market open/market close). The best way to know for sure would be to give it a test. If doing python you could add on another 20-50ms for the python interpreter depending on what you do inside your algorithm.
IB market orders can take several seconds to fill, this is IB's delay though not ours. You can tell QC to send orders asynchronously to skip waiting for their responses.
