Slippage — when an order doesn’t get filled or gets filled at a worse price than anticipated.
In every trade there are two parties one, the maker and the other, the taker.
The maker creates an offer. We call this “making a market.
The taker chooses to take the makers offer.
The amount of coins on offer by makers is known as depth.
When there are not many makers offering, this is called a thin market. When there are many makers, it’s a deep market.
