That is somewhat proprietary however i will say the real issue is that "before, during, and after" are delineations that are mostly only visible with hindsight.
I actually do the opposite of going in pre-report or on release of the report, have it automated cause I am too slow, LOL and it watches 40 markets, different reports/different markets. But I fade initial moves based on one minute charts. I have developed couple different entries based on how crazy market is. But I am not greedy and risk/targets are tight. I rather have very low losing percentages than high winning percentages. This allows heavier volume. Entry Stops are placed after price reaches certain quantifiers. I stopped the "Could'a would'a should'a thoughts long ago, they are negative thought patterns and not good for brain. I am very happy to be a singles and doubles hitter in Day Trading.
Only some people can read market and manage their trades well . Most of them who trade in news blindly act upon news release . It becomes a gambling for them , It is not necessary all news are true and profitable for them.
