24-Hour / Overnight trading

These brokers run an overnight session: Charles Schwab (thinkorswim), Interactive Brokers, Robinhood, E*TRADE (Morgan Stanley), Webull, Moomoo, Firstrade. Each publishes its own list of symbols admitted to that session, and those lists are typically limited to large-cap index members. We do not track them per symbol, so check whether PLXis on your broker’s list before planning an overnight order.

Overnight sessions route through ATSs, typically have wider spreads, accept limit orders only, and offer no guaranteed fills.

Penny stock / OTC routing

PLX trades on the OTC markets. Broker support varies sharply by tier (OTCQX, OTCQB, Pink Current, Pink Limited, Grey). Fidelity and Robinhood exclude pink/grey entirely. For short-locate on small-caps, Interactive Brokers and the day-trader specialists (Cobra Trading, SpeedTrader, CenterPoint) have the deepest inventory.

A true overnight session is offered by Charles Schwab (thinkorswim), Interactive Brokers, Robinhood, E*TRADE (Morgan Stanley), and others, but each admits only its own list of symbols — usually large-cap index members — so confirm PLX is eligible with your broker. Overnight sessions route through ATSs with wider spreads and limit orders only.
