Tick - Preference Inter Market Arbitraj. Not that PIIMA, sickos. TPA is a little-know pure-arbitrage strategy in which you can choose 1:1 intermarket correlations for sick arbitrage profits! You choose the tick-preference! You choose the 1:1 correlated offset!! Here's an example: Short Dec 2020 CL from 47.50 (not that near-term garbage in the 30s. Take the contango!) COVER in UWTI spot at 1.80! That's a LOCK that NETS you 45.70 per contract... BUT WAIT! YOU CHOOSE the tick (tick preference*)! Yes, you can choose to take profits in CL ticks, not UWTI. That's $45,700 in pure profits.
I think if you trade it right there's a look back where you can choose which price you print the WTI and the CL.
We need many/moar examples. This is a burgeoning space that has virtually no capacity issues! It shall never be traded flat!
One of my personal favorites is Long GOOG/BRK_A. The best var is during reporting-period... you wait for GOOG to report AH and ***BUY*** GOOG when it's halted. THIS IS THE KEY TO THE BEST FILL. THEN you cover in BRK_A; not the piker-s*** class-B peasant stuff. BINGO! $201,857.23 in INSTANTANEOUS profits. Per lot!
OK...I have several investors who would sue my ass off if I ever made public this strategy but this is among friends. A year ago I noticed that when ES traded at a certain value and moved higher I could buy the front month ES and then buy the front month YM and hold until the high of the day and close both for significant profit. It worked once perfectly and then I decided to stop trading it so I would not destroy the edge.
See guys? This is how free-discussion results in ever more bangin' arbitrageses. I would never have considered adding options to a halted-buy.
