Minecraft Hypixel-Api Bin Sniper

Hello im trying to create a minecraft hypixel skyblock ah sniper bot but im keep running into a traceback -

Traceback (most recent call last):
  File "C:\Users\maksi\OneDrive\Pulpit\testingsniper\testing.py", line 146, in <module>

    if prices[index][1] > LOWEST_PRICE and prices[index][0]/prices[index][1] < LOWEST_PERCENT_MARGIN and auction['start']+60000 > now:
TypeError: '>' not supported between instances of 'float' and 'str'

This keeps happening to mee and i don't know where to put a float or str function or to even put it there. Here is the line of code that crashes

# if the auction fits in some parameters
if prices[index][1] > LOWEST_PRICE and prices[index][0]/prices[index][1] < LOWEST_PERCENT_MARGIN and auction['start']+60000 > now:
    results.append([auction['uuid'], auction['item_name'], auction['starting_bid'], index])

i really don't know what to do to make it work.
