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.
