Yes it check the volume and the price of 3000 open orders. I can make it to count the whole orderbook and to set a number of open order to count that is a part of them that's possible. That's also a good point because it will eliminate the bug that could occur if the orderbook is smaller that 3000 offers but I have to count the whole orderbook anyway for set that number automatically. Actually it count from the highest bid and the lowest ask so it can find the buy/sell wall easy with 3000 offer but that's a parameter that have to be adjusted when the orderbook depth if it change significantly.
