Magnifying Glass Magnification Formula
A magnifying glass is any positive lens with a focal length of less than 250 mm. The approximate magnification M provided by the lens is calculated by dividing its focal length by 250. For example, a lens with a focal length of 50 mm will give an increase of M = 250/50 = 5×.

Does anything depend on the diameter of the magnifying glass? Probably the size of the field of view only? What is the diameter of a magnifying glass glass?

How does AUTO BIDDING work
This is a function that helps you place bids automatically in case your bet is interrupted.
For example, current lot price is UAH 120. You are ready to bargain up to UAH 5 000. Enter 5 000 in the field "Automatic bargaining" and click "Place Bet". As a result, your new rate will appear, but not in the amount of UAH 5 000, but only UAH 121. In this case, the system will remember that you are ready to bargain up to UAH 5 000, and will make the necessary bids for you if the price continues to rise.
Let's say another participant places a bet of UAH 2 000. Then the system will automatically place your bet of 2 001 UAH. And only if someone places a bet more than UAH 5 000, you will receive a notification that your auto rate has been interrupted.
