Hey! Nice to be here. I am new to algo and automated trading so I asking it here if my tesk is even posible. my tesk is, lets say there is 1000 contract to sell at the corrent market price, I want to buy the market price but I want it only when there is 100 contracts left on that level, So I basiclly want my order to be triggered only after 900 contract sold. somwthing like this can be done? Thank you!
