Cheating

[I_will_win_this]

This is ridiculous. With a 20 minute delay it's very simple to cheat. Find a high price mover, buy it in the competition before the price rises, wait 20 minutes tor the increase to register and then sell. Sure - to compensate, execution is delayed by 20 minutes too, but so what, once it's up, it's up. It's very unfair and to be honest, although I do not like to accuse, makes me wonder how sino.s knew to choose a stock that then rises 99% in a day. Pure luck? Maybe. But perhaps that should be investigated.
In the meantime, 2nd place as promised.

Execution is delayed 20 minutes but you get it at the price when you actually click the button (well, you should do but there is actually a 5 minute anomoly!)

Do I get a prize for paying the highest to buy GMC?
It was nowhere near 22.5 when I clicked the button. Honest, guv!
