The Average True Range indicator is really rather simple, as the name suggest it is simply the average of the True Range of the past X bars. Ok, so then what is the True Range?
Well instead of just the range of a session which is simply the high – the low the True Range is actually calculated slightly differently (although some basic ATR indicators get this wrong).
In most cases it will be the same as the high – low but actually there are 3 potential ways of calculating a day’s true range depending on the circumstances.
I don’t want to go into details about the variances but the three methods for reference are:
High – Low
High – previous Close
Low – previous Close
Most commonly used ATR setting is for 14 periods and more frequently 14 days, however personally I use the 20 period (and more specifically 20 day) ATR in all of my trading.
Why is this?Well it’s because I know my statistics for my currency pairs and I know that just under 80% of the time price will stay within a range that is defined by the 20 day ATR.
In the chart below you can see how the ATR is normally plotted. Here I have used my 20 period ATR.
As you can see typically the indicator shows the ATR in a Pip value, in the example above the ATR reading is showing an Average True Range of 150 pips.
So how do people use the ATR?Well a lot of people use the ATR as a good indication for profit targets. For instance if I know that my ATR is 100 pips and I am taking an intraday trade, then setting targets at the 100 pips could be a stretch so on a daily basis I might target the 80 pip mark instead. If I know we have a non-news day and price has already moved 100 pips on an ATR value of 110 pips, then I know realistically price is unlikely to move much past this (that isn’t to say it won’t it is simply a lower probability)
To make the ATR a little easier to use and more visually accessible for spotting trade setups, we came up with an indicator which is a slight tweak on the ATR.
Introducing ATR Boundaries
The key to this chart for today is the orange lines surrounding price; these are my Daily ATR price boundaries created by Adding and Subtracting the Daily ATR over a 20 period from the previous days Close price.
I use these ATR Boundaries to give me clues to potential reversal areas, price breaching these lines is likely to pull back to find better value; combine these with some order book information and you have a really simple but extremely powerful strategy for trading 4hr charts.
A really simple strategy that works nicely is to look for pin bars at a test of the ATR boundaries.
On the chart above I’ve overlayed the 20 Day ATR on a 4hour chart and loaded up the Pin Bar indicator which automatically highlights pin bars. With nice clear signals this a great swing trading strategy for you to try. Pin Bar indicator will also automatically suggest a stop loss, entry point and target levels on your charts for you so all you have to do is set the orders at those levels.
In fact using these bands along with any traditional indicators, it is possible to quickly get a decent strategy together. A really effective way of using them is to overlay the Daily Order Flow Trader signals onto the H4 chart. We want to see price moving in the direction of the Daily OFT signal and then we wait for pullbacks into the ATR boundary levels to trade for a resumption of the trend, as seen below .
The red band around price comes from the Daily OFT signal which is showing volume flowing into a bearish trend so as we see price pullback into the upper boundary we can fade the move with a low risk trade looking for price to continue lower.
