Because of a bug in polymarket. I lost like $6k.
on frontend, I was being shown my open position but the position was already sold.
Initially when the position was in low 20cents, I had initiated a sell order at 30c but cancelled it when it was 25c and it was succesful.
I did not see any orders in open orders and I could still see my position in open position.
and I was constantly monitoring my position. the values were changing. so it isnt like it was stuck.
And now when it is at 83c, I tried to sell and it was not working.
I refreshed and found that I was no longer in position and that cancelled order of 30c was executed.
This isn't the first time something like this has happened.
I have noticed your sell orders will be executed if position clearly goes your way ( few cents above )
and you'll be stuck with position if it touches the selling price or even a cent higher.
is this a bug or scam?
an unfair advantage to market makers??
eitherway, this isn't expected from multi billion dollar company.
if you are using polymarket, use it for fun but do not trust them with big money.
