Every thing is working but bot updates only 10 buy orders. What am i doing wrong?
I did first run, he set up and start updating my orders, than i paused and manualy set few more
buy orders and bot seems like dont see them he just update old orders.

If you open logger as per link in my signature and activate writing logs you will see additional info about bot decisions.
As a rule bot does not update several orders of the same type in the same station.

If margin between buy and sell orders is enough to get profit, bot will update it. If not, it will "park" order - slightly reduce buy price to avoid buying items with lowering price. If there is not sell or buy orders bot cannot calculate profit and will not update orders too.

I should see log to explain better.
