API returns 0 for daytrading buying power although interface shows positive

I am not sure why, I had this error before few months ago. One of my accounts show 0 for buyingpower while the interface shows that I got my usual balance. I dont have any maintencance margin so my trades wont execute today…

What is the cause for this?

Same here, I’m locked into any position I opened today currently.
