# Calculators

Watching the markets and making informed, educated decision can be a complex and challenging task.

STO’s calculator will help you contextualize data, recognize market patterns, trends and the movement of instruments. Use the Fibonacci, Deal Size and Correlation to calculate important support and resistance level for multiple instruments.

## Fibonacci Calculator

It is assumed that Fibonacci levels help to determine possible levels of correction in the price of a trading pair. Key levels are thought to be 38.2%, 50% and 61.8% as they represent the strongest support/resistance levels. Levels for a corresponding direction in the price movement will appear in the "Uptrend" and "Downtrend" fields.

How to use
In the appropriate fields, type in the lowest and the highest price of a considered price movement and press "Calculate". The calculator will return expected correctional levels for this movement.

## Deal Size Calculator

The deal size calculator helps traders to choose an optimum size of the opening lot depending on the accepted level of risk.

How to use
In the "Symbol" field, choose your required instrument. For example, EUR/USD. In the "Account size" field, indicate your account balance. For example, \$100. In the "Risk" field, indicate the size of risky capital as a percentage of the account size. For example, 10%. In the "Pips to Stop Loss" field, indicate how many points away should Stop Loss be placed at. For example, 20. To get the results, press "Calculate". With the values mentioned above, the recommended deal size will equal to 0.05 lot.

## Correlation Calculator

Use chart to visually see the connections between instruments and calculate a correlation coefficient. Choose between currency pairs and commodities, timeframe and number of periods.

- weak (0 to +/- 0.2)
- low (from +/-0.2 to 0.4)
- average (from +/-0.4 to 0.7)
- high (from +/-0.7 to 0.9)
- strongest (from +/-0.9 to 1)

The Correlation calculator is a useful analytical tool that helps to make a sound trading decision when using a strategy, which is based on diversification and hedging against risks.
