In the world of finance, an odd lot is an order that does not fit into traditional board lot sizes. This means it can consist of any number of shares, rather than being a multiple of the standard lot size. This may seem confusing, but it allows for more flexibility in trading and can be beneficial for investors looking to buy or sell a specific amount of shares. So, don't be thrown off by the term "odd lot" - it's simply a way to describe a non-standard order size.
