Bid
Bid refers to a price that a potential buyer is willing to pay. When you want to sell an asset, you look at the Bid price because this is how much a buyer is ready to buy it for.
On a CFD-based platform, such as MyBro, the Bid is the price at which you open your SELL (Short) position and close your BUY (Long) position.
Since the Bid is what a buyer is willing to pay you, it is always lower than the Ask.
