Inconsistent final outcome for BTC 5-min UP/DOWN on polymarket

Trading Strategy


Anyone has experience trading on polymarket? 
i encounter a very strange behaviour for 5-min BTC UP/DOWN marekt. On polymarket website, the initial price is 75,027.53 and chart show 75,009.03 at period end. I expected the final outcome should be DOWN
However, polymarket mentioned it is UP with final price "75,065.44" instead of "75,009.03". Why the result is not consistent? Is it a bug or I misunderstand something? 

In fact, I encountered multiple times for this situation which lead to some losses...

As highlighted in their rule, Polymarket uses chainlink BTC spot price as at the period start and end time to determine the initial and final price. The price you observed from their website is just based on their internal data source and it is for reference only.
