He shorted oil at 94.00 so probably up another 15K today

Quote from RedSun:
Also, say you get $10k capital. With intra-day margin, you get keep 4 CL contracts. If market moves $2 and you catch it all, this is $8k profit, or 80%. And if you trade intra-day and catch more than $2, then the return would be higher than 80%.
How this is impossible? Easy math.
