I am a product manager & am currently testing a prediction market strategy; my preference is betting NO rather than YES, which would receive more value. However, the mistake happened several times. The reaction of switching YES to NO is slow. Although the data is loaded from YES to NO, the order placed is still the YES order & cannot be refreshed, even after killing the app. YES / NO market should be placed equally on the bottom of the ordering page. Besides, you guys don't have the normal limit order & time limit order function either, which are the necessary functions for the prediction market. These bad designs make me lose today's LAC game again. For these situations, personally, I am really doubting whether you guys have ever done the complete test these trading functions & do the complete thinking of this product iteration. I will no longer use any trading function on Phantom.
