I like to backtest intraday on about 3000-4000 stocks. But I like to keep the
entire universe of stocks daily data so that on a monthly basis, I can
determine the stocks that I want to do intraday backtesting on if they meet the
parameters.
Does that mean that all that intraday data will be collected on my machine and
that's what I'll be backtesting against?
What if my ISP or PC goes down and I miss some data. How are the gaps
filled and when?
If that's the case, I'd almost think that with TSPro, you're back in the data
maintenance business.
