A liquidity program can make a market look generous: post quotes, earn points, collect a reward. The hard part is keeping a quote eligible while the market moves around it.
The reward formula is only one line in the plan. Spread, size, time at the top of book, cancellation rules, and inventory can matter just as much.
Read the eligibility rule
Start with the exact measurement window. Is depth measured at snapshots, continuously, or by executed volume? Does a quote count if it is far from the midpoint? Are both sides required?
A hypothetical maker posts 100 shares at a narrow spread, then cancels after a price move. If the program measures resting time, that trade may earn less than a wider quote that stays live. The example explains the mechanism; it is not a current reward estimate.
Put inventory beside the reward
Quotes can fill selectively. You may collect one side of the book and end up long an outcome just as the market reprices. A reward cannot be evaluated without the position that earned it.
Track filled size, average price, fees, inventory value, and the reward actually credited. Keep canceled and expired orders in the log so the denominator is visible.
Test the boring case
Replay a volatile hour with the program's published rules. Mark every moment your quote would have been outside the band, too small, or missing one side. Then add realistic delays and partial fills.
If the result depends on perfect uptime or instant cancellation, call that out. A liquidity program can be useful for market quality while still being a poor fit for a small account.
Read the current terms before committing funds. The first question is not how large the reward looks. It is whether your quote-management process can meet the rule without taking an inventory risk you did not plan for.

A note on risk
Prices can change and positions can lose their full value. Examples are educational, not promises of returns.
