# Stock live trading

Bottom-fishing Boeing, Boeing plummeted.

Bottom-fishing platinum, silver and gold both surged, only platinum plummeted.

Trading Tesla both ways, Tesla has big fluctuations every day, only yesterday it was range-bound.

The strategies that could be used before are now all unusable.

The reason they weren't used before was because the option premiums were expensive, the reason they're used now is because the option premiums are cheap. As a result, the market makers have a firm grip on the psychology. When premiums are expensive, it will fluctuate wildly; when premiums are narrow, it won't fluctuate. It really feels like market manipulation.
