Now if we combine that entry into the ASX200 with the Triple Witching Day, which I pointed out before, I think we got it covered!

What Is Triple Witching? Triple witching is the simultaneous expiration of stock options, stock index futures, and stock index optionscontracts all on the same trading day. This happens four times a year: on the third Friday of March, June, September, and December. Because three options classes that could share the same underlying securities' expiration all on the same day, it can cause increased trading volume and unusual price action in the underlying assets.Triple witching is the simultaneous expiration of stock options, stock index futures, and stock index options contracts all on the same day.Triple witching occurs quarterly—on the third Friday of March, June, September, and December.

Triple witching days, particularly in the final hour of trading preceding the closing bell—called the triple witching hour—can see increased trading activity as traders close, roll out, or offset their expiring positions.
