How do you experts determine the direction of the market when bots starts placing several buy or sell orders of 0.0001 and increasing those orders by just 1 digit? i.e.,

buy/sell 1 unit of x @ 0.00001234, @ 0.00001235, @ 0.00001236, @ 0.00001237, @ 0.00001238, @ 0.00001239 to let's say 0.00002400.

Please, I need an answer to this ^ .
Thank you.
