In Episode 7 of The Liquidity Game, we investigate the hidden side of modern market structure: dark pools, alternative trading systems, internalization, and off-exchange trading.

Why would an institution want to trade without showing its full order publicly? What exactly is a dark pool? How is an ATS different from an exchange? Why do wholesalers execute so much retail order flow away from public markets? And what happens when a massive institutional order needs to trade without advertising itself to every trader watching the book?

We break down:

dark pools, ATSs, off-exchange trading, midpoint execution, internalization, block trades, hidden liquidity, trade reporting, market impact, information leakage, fragmentation, price discovery, and the limits of Level 2.

We also examine some of the biggest myths surrounding hidden liquidity:

Does a huge dark-pool print mean an institution is buying? Are dark-pool trades invisible forever? Is off-exchange volume automatically bullish or bearish? Do dark pools exist to manipulate retail traders? Can institutions buy huge positions without moving price? And if Level 2 doesn’t show every buyer and seller, what exactly are traders seeing?

The deeper question is:

How do you understand price discovery when some liquidity is visible before the trade and some only becomes visible after it happens?

What actually happens when you short a stock?

In Episode 6 of The Liquidity Game, we follow a short sale from the moment a trader presses Sell Short through the hidden securities-lending system that makes the trade possible.

Where do the borrowed shares come from? Who owns them? What is a locate? Why do some stocks become hard to borrow? Why can borrow fees explode? What happens if the lender wants the shares back? And what does it really mean when short interest becomes extremely high?

We break down:

stock borrowing, locates, lenders, brokers, prime brokers, short-sale marking, hard-to-borrow inventory, borrow rates, utilization, recalls, forced buy-ins, settlement, fails to deliver, Regulation SHO, and the mechanics behind short squeezes.

Then we investigate some of the most controversial claims in retail trading:

Does high short interest guarantee a squeeze? Does 100% utilization mean no shares exist? Are fails to deliver evidence of illegal naked shorting? Can the same shares effectively support multiple layers of short exposure through legitimate market activity? And what actually forces a short seller to cover?

The central question:

When you sell a stock you don’t own, what machinery has to exist underneath that trade?

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.
