To be honest, compared to the strength of the upward push, the downward pressure isn't particularly strong. That day, when it surged, it went from 94,000 all the way up to 107,500 without any pullback. There shouldn't be much fluctuation this morning, but in the afternoon there should be a cleanup of high-leverage long positions. It's advisable to enter with a light position now; in case the market maker doesn't want people to get in, just take a small profit. If it really wants to clean up and reverse, then add to your position. Manage your position well and don't get washed out.
