Schwab Has Gone 'Liquidation Only' On Their Retail Commodities Platform (wheat , corn)

Usually it is the exchanges that do this but here is Schwab following in the tracks of Robinhood.* 

Schwab won't let anyone buy Chicago Wheat, Kansas City Wheat and Corn options.

Closing orders only.

A Heads-Up To The Gamestop, AMC etc. Crowd: They Are Going to Change The Rules On You

Market structure is the most important and least understood factor in the entire short-squeeze game.

And if you don't understand every dependent clause and every comma versus period in the rules and regs you are in for a shock.....

That was the day before Robinhood decided that for the safety of the firm it would be best if they stopped facilitating purchases of AMC and GME and a few other issues, at least for a while, until they could get their net capital shored up.
