The average daily range formula is as follows:. Equations can be a bit heady and often confuse otherwise simple calculations. An iterative approach to calculating the ADR is outlined as such:. First, anyone unfamiliar with candlestick representation of stock prices should check out this article. In the illustration below we can see the Daily Range calculated for each period over a 5-day interval K and then added together and divided by K.
This gives us the ADR for that period. This image depicts a stock price that is gradually becoming more volatile over a 5-day period. The first period has a Daily Range of 2 while the last two periods have a daily range of 4. The average daily range here is 3. To deploy the ADR as an analytical tool we will implement our logic so far as a Python function. Keeping in mind our algorithm outlined above, we can implement the ADR in Python as follows:.
Here we see our result matches up to the manual calculation from the illustrated process above. This one-liner will make calculating the ADR for some real-world data a bit less syntactically cumbersome. We can get this data with the following code:. For each period in our interval, we need to calculate the daily range from the High — Low calculation. This is done using the apply method of the DataFrame object as such:. We now have a third column reflecting the difference in our daily High and daily Low.
Next, we need to calculate the average of these values over a preceding period. To do this—effectively calculating a moving average—we will use the rolling method of the DataFrame. Before we calculate the Average Daily Range we need to define our lookback period. A common value for this is 20 periods and what we will use here.
This decision means that every ADR value we calculate is reflective of the previous 19 periods of price action plus the range of the current period. This can be achieved via the following code:. A few things to note: first, we see a new column has been added for the ADR. Secondly—and most important—we see a value of NaN for the first entries.
This is because there are fewer than 19 20 — 1 preceding values for these dates. We need a minimum of 20 values to calculate the ADR since that is how we defined our lookback window. For example, if we were to print out rows we can see where the transition takes place:. In row 20 for the date , we have our first DR value where there are enough preceding values to calculate the average using our period lookback window. The ADR is a great measure of volatility and can help signal a great opportunity to traders and investors.
However, it has the shortcoming of being very specific to the price action of a single stock. However, the percent change in price would still be comparable. To use the ADR as a screening tool, such that one can compare volatility among different assets equally, we need to modify the ADR formula to reflect a percentage change rather than a fixed dollar change.
For this, we need to adjust our algorithm as follows:. This gives us an ADR representing a percentage change in price which allows comparison between assets with wildly different prices. The following image reflects the update to our ADR algorithm:. Setting tp and sl depend on your strategy, winrate, RR; however, as a general rule, the amount of ATR for SL is equal to 1x of atr where x is the amount of atr.
One of my strategies has 1. Interesting stuff you got here brother. I was just watching trading in the zone. And so much is related to your study. Thank you. Regards Dhiren. I also have a question! If is the daily average what is , is it the monthly aveage or yearly average or what?
It is not explained in the text. It was related to the process of calculation before averaging the 7 years. I was working on a 7-candle circle, instead of 5, for a week and the pictures were for that — nothing important. I been thinking of doing a similar study as I want to know the most volatile currency pair to trade but you have done such a great job and more complete than I probably would have thought to do.
