The order book is where traders place bids and asks for $BTC . Bids are what buyers are willing to pay, while asks are what sellers are willing to accept. The difference between the best bid and ask is the spread. For example, if the best bid is sitting at 35000 and the best ask is at 35050, the spread is 50. Market depth refers to the total amount of bids and asks at each level. A deep market has many bids and asks, making it more stable. In a shallow market, there are fewer bids and asks, making it more volatile. Understanding order book mechanics is key to navigating markets like $ETH and $LTC . Trading with knowledge of bids, asks, and spread can help traders make informed decisions. #tradingbasics #orderbook #marketdepth
