Best Indicator for Forex Trading

Below we will discuss a few of the more useful indicators and how they can be used.

Best Indicator for Forex Trading

Average True Range (ATR): 

Developed by Welles Wilder, ATR is an indicator that measures volatility. ATR can be used for calculating where to place stops, profit targets and position sizing.

Wilder started with True Range (TR), which is defined as the greatest of the following:

  • Current High less the current Low
  • Current High less the previous Close (absolute value)
  • Current Low less the previous Close (absolute value)

Typically, the Average True Range (ATR) is based on 14 periods and can be calculated on an intraday, daily, weekly or monthly basis as follows:

Current ATR = [(Prior ATR x 13) + Current TR] / 14

  - Multiply the previous 14-day ATR by 13.
  - Add the most recent day's TR value.
  - Divide the total by 14

Moving Averages

Moving averages smooth the price data to form a trend following indicator. A simple moving average is formed by computing the average price of a security over a specific number of periods. Most moving averages are based on closing prices. Moving averages are generally used to measure momentum and define areas of possible support and resistance.

A simple 5 day moving average is calculated as follows

Daily Closing Prices: 12,13,14,15,16,17,18 

First day of 5-day SMA: (12 + 13 + 14 + 15 + 16) / 5 = 14

Second day of 5-day SMA: (13 + 14 + 15 + 16 + 17) / 5 = 15

Third day of 5-day SMA: (14 + 15 + 16 + 17 + 18) / 5 = 16

RSI is a momentum indicator which compares the magnitude of recent gains to recent losses in an attempt to determine overbought and oversold conditions. It is calculated using the following formula:

RSI = 100 – 100/(1 + RS*)

*Where RS = Average of x days’ up closes / Average of x days’ down closes.

RSI oscillates between zero and 100. The indicator is overbought when above 70 and oversold when below 30. Signals can also be generated by looking for divergences.


MACD (Moving Average Convergence/Divergence) is used to spot changes in the strength, direction, momentum and duration of a trend.

MACD is calculated as follows:

MACD: (12-day EMA - 26-day EMA) 

Signal Line: 9-day EMA of MACD

MACD Histogram: MACD - Signal Line
