#### Buy price with Orderbook enabled
When buying with the orderbook enabled (`bid_strategy.use_order_book=True`) - Freqtrade will fetch the `bid_strategy.order_book_top` entries in the orderbook, and will then use the entry specified as `bid_strategy.order_book_top` on the `bids` side of the orderbook. 1 specifies the topmost entry in the Orderbook - while 2 would use the 2nd entry in the Orderbook.

Freqtrade will then validate each of the orderbook steps between `ask_strategy.order_book_min` and `ask_strategy.order_book_max` on the `ask` side for a profitable sell-possibility based on the strategy configuration and will place a sell order at the first profitable spot.
The idea here is to place the sell-order early, to be ahead in the queue.
A fixed slot (mirroring `bid_strategy.order_book_top`) can be defined by setting `ask_strategy.order_book_min` and `ask_strategy.order_book_max` to the same number.
