The a/c/e platform does not transmit all ticks.Quote from Daxman_Cometh:
It behaves erratically. And even if you are using a super-fast platform, i.e. TT's X-Trader, prices can disappear much faster than you can click on them Today I sold it at 9381, puked em at 9386 at 2:04 pm CST, hitting my daily loss limit. When I sold them, the S & P e-minis were sitting still. Nonetheless, the Dow spiked up, immediately before cruising 100+ points down. Frustrating, to say the least. . . . . .
