Securities/Trading Standards and laws?

Obviously no one may be an expert here but to anyone's best knowledge....I have an issue with trading on coinbase recently and want to know the answers to a few questions. 1. Is there some sort of minimum standard of liquidity an exchange is expected to maintain to avoid price manipulation? Specifically 15-20% one minute candles for something traded in it's futures contracts? I know its a liquidity issue because the spot price was not fluctuation more than 1% during that time and this volatility was experienced during the roll over contract opening up to the next month. 2. Does the roll over contract process being an automated and unstoppable process during this time violate any transparency law? You click "roll contract" and it automatically continually executes market orders partially of fully filling them during said 15-20% volatility over about 10 minutes with no way to view what prices the orders are being executed at and no ability to stop it? It seems both of these issues combined is an environment ripe for manipulation and anti consumer and outside the bounds of "acceptable risk". Didnt FTX get charged with stuff like this?
