Is there a historical list (date/time) of news events that had a substantial influence on the SP500 volume and/or price?
By "substantial" I mean that for example the volume jumped 300% and above of the 20 minute moving average volume, and that the price move was significant.
I'm asking because when trading live, I would surely close my positions before those events. Therefore, I need to follow the same rules when backtesting strategies and automatically exclude times of great volatility as otherwise this can create a bit of a mess for the more sensitive strategies on shorter time frames.
I could try to make such a list by myself by looking at spikes in volume, but i'm not sure this is accurate enough. Secondly, unforseen or un-announced events can also move the markets, and assuming I had knowledge of those is cheating the backtest. For that reason I'd like a list of only the events that were announced and had taken place. One example would be the Fed announcement yesterday that there would be no QE any time soon.
If there is only a list of events that include those that had no impact, that's fine too because i can filter them out.
The farther back in time it goes, the better.
Cheers
