1 out of 5 shares purchased by retail investors is executed by Citadel securities, and the ratio for options contracts is higher.

$AMC Entertainment (AMC.US)$ Citadel runs the options chains. Please, people, realize that they can move the share price to the price that will benefit them the most. So 3 or 4 out of 5 option contracts are executed by Citadel. So, the dark pool volume is around 50 percent of the days volume and executed by Citadel. they only do so with certain stocks, which is supposedly 200 stocks. I think there's is more than that. Amc has been pulled and pushed down by the market maker. This is the reality for Amc stock. They don't always have full control of the price but definitely have a strong handling of the share price. The new rules coming from the SEC have put Citadel on edge and filed a lawsuit against the SEC. The CAT system came out in 2012 which is supposed to track and report the numbers and transactions on the trades on the stock market but they made the sec delay the market from using the new technology.By influencing political figures and sec with money and lawsuits. Almost every month, the fraudulent actions by the companies in the market are getting caught. The biggest banks and firms only get fined small amounts compared to the profits. This is why Amc is where it is today.
