What actually happens after you press Buy or Sell?

In Episode 5 of The Liquidity Game, we follow a retail stock order from the trading app all the way to execution and uncover the hidden market infrastructure operating in the background.

Most traders imagine their order simply goes to “the stock market.” In reality, U.S. equities trade across a network of exchanges, market makers, wholesalers, alternative trading systems, and other execution venues.

This episode explores:

• what happens after a retail order is submitted
• broker-dealers and smart order routing
• exchanges versus wholesalers
• market makers and internalization
• ATSs and off-exchange trading
• displayed versus hidden liquidity
• the National Best Bid and Offer
• price improvement
• market orders and limit orders
• queue position and execution probability
• slippage and thin liquidity
• maker-taker fees and exchange rebates
• payment for order flow
• best-execution obligations
• why two brokers may route similar orders differently
• why commission-free trading still has an economic model behind it
• why Level 2 does not show every source of liquidity
• what Rule 605 and Rule 606 disclosures can tell investors

We also examine some of the biggest misconceptions in retail trading:

Does every order go directly to Nasdaq or the NYSE? Does payment for order flow automatically mean worse execution? Do dark pools secretly control stock prices? And if the best displayed ask is $50.02, how can your order sometimes fill at a better price?

The central question:

When you click Buy, who actually receives your order and who decides where it gets filled?

The Liquidity Game explores what happens beneath the chart: market structure, liquidity, risk, psychology, and execution.
