How to Use the BidAsk Calculator
This BidAsk Calculator helps you determine the spread and margin between the bid price and the ask price in a trading scenario. Here’s how to use it:
Step 1: Enter the Bid Price
 This is the highest price that a buyer is willing to pay for a security or asset.
 Example: Enter “1.430” in the “Bid Price” field.
Step 2: Enter the Ask Price
 This is the lowest price that a seller is willing to accept for the security or asset.
 Example: Enter “1.675” in the “Ask Price” field.
Step 3: Calculate the Spread and Margin
 Click the “Calculate” button to compute the spread (difference between the bid and ask prices) and the margin percentage.
Formulas:

Spread: The difference between the ask price and the bid price.
$$\text{Spread}=\text{AskPrice}\text{Bid Price}$$

Margin: The spread as a percentage of the ask price.
$$\text{Margin}=\left(\frac{\text{Spread}}{\text{AskPrice}}\right)\times 100$$
Example Calculation

Bid Price: 1.430

Ask Price: 1.675

Spread Calculation:
$$\text{Spread}=1.6751.430=0.245000$$

Margin Calculation:
$$\text{Margin}=\left(\frac{0.245000}{1.675}\right)\times 100=14.62687\mathrm{\%}$$
