Comes down to interest really which is about money west of the Atlantic. Oh and of course bragging rights. I see OT has suggested his system to a T2W thread. Why not host it OT on ET and see if there is any interest ? Of course prizes would help.
T2W has 15 players for the weekly projections game. I think ET prefers to attract more of very short time-frame players. Limited EOD players. Only few EOW players, if any. Just my guess.
You can count me in if it's EOW + prizes. I hosted the T2W thread for 3 years, perhaps you have the time ?
I would think you should start soonest the same competition here on ET first before securing funding from ET. Traders currently doing very-short term trades can still use their same systems for your competition game, particularly when offering prizes. Sorry, No, don't have the time for it for now. However, might try a few trades later in the future after you starting it on ET (with the expectancy format).
How about just limit the trading competition to those who regularly post in the "Gotta love ZERO RISK in the SP500 = $$$" thread. That would, at least, add entertainment value.
