What are Bid and Ask prices
The two lines on your chart represent the Bid and Ask prices.
Bid price is the highest price buyers are willing to pay
Ask price is the lowest price sellers are willing to accept
The difference between them is called the spread.
What this means
Every trade is executed using these prices:
You buy at the Ask price
You sell at the Bid price
This is why there is always a small difference when entering or closing a trade.
