  "account": "Understanding the lifecycle of Polymarket TWAP markets is crucial for developing safe and reliable trading bots. At first glance, a market may seem to simply open, trade, and then close, but this oversimplification can lead to incorrect decision-making. The key distinction is to recognize that a market can exist in several states simultaneously and that multiple timestamps should be considered to accurately determine its lifecycle.\n\nThe Polymarket market lifecycle can be modeled using a state-estimation problem that includes the following states: DISCOVERED, ACTIVE, ENDING, CLOSED, RESOLUTION, and RESOLVED. The end of a market's defined interval (the \"market clock\") is not the same as the market outcome (the \"resolution clock\"). Trading bots must distinguish between these different clocks to make appropriate decisions.\n\nFor TWAP markets, the resolution is based on a Chainlink-generated TWAP, which creates a clear separation between the trading state, oracle state, and resolution state. A trading bot should not assume that the market has resolved simply because it has reached its scheduled end time. Instead, it should wait for authoritative market-state information before transitioning to the resolution state.\n\nWhen building a trading system, it is essential to measure relevant market-state information at multiple timestamps and store these observations with their respective timestamps. This allows for a more accurate reconstruction of the market's lifecycle and helps to identify any potential bugs or issues related to state transitions.\n\nCommon mistakes made by traders include confusing the end time of a market with its resolution, assuming that a closed state means the winning side is known, and assuming that a spot price determines the outcome for TWAP markets. To avoid these pitfalls, it is recommended that trading strategies consume pre-built market-state information rather than attempting to reconstruct the lifecycle logic independently.\n\nTo test the effectiveness of lifecycle logic, a simple synthetic experiment can be conducted. By generating market events with specific timestamps and states, and then feeding these events into a deterministic state machine, developers can verify that the system correctly identifies state transitions based on multiple authoritative fields rather than relying on a single timestamp.",

How to Detect TWAP Market Lifecycle States in Polymarket A short-duration crypto market can look simple from the outside: a market opens, traders trade it, the time window expires, and the winner is determined. For a trading bot, that mental model is…",
