The trading software was manipulated, especially when I traded options. The graph of K line was biased in CA, compared to other software. So was the K line in software of CA. The options weren’t settled when the time was beyond the limit time sometimes, until you lost money. What’s worse, let teachers profit, let us lost money by manipulation using network latency until there was no money in our accounts! Bloody lesson, I was swindled out of 250,000, deciding to expose this fraud platform: CA. If you are the same with me, call the police or sue immediately.
