Intraday this is a huge buy right here right now.---Never risking any more than 2 percent of your liquid net worth of course.
Why take the risk at all? A market that's making new intraday lows is not a market to get long. Once a bottom has been established and tested, then yeah okay, there's someone defending it with a bid so getting long is logical and you have a point of reference to bail.
In any other case, you're just picking bottoms and your stop is just fuel for the next run down.
