yes, you are right many brokers offer lots of lot sizes depending on your account type. But, which lot size do you use for forex trading depends on your capital and experience on a demo account ... My advice is to first use a small lot to understand the real forex trading platform when you will experience forex so you understand how to measure lot lot better for your account. and all depends on your broker and also what your experience is in your financial background, if your broker allows 0.01 it is not like that and taking 20 pips to make 2 $ for a week continues to increase lot size every week
