What is average true range (ATR)?
Average true range is the averaging of 14 periods intended to smooth out short term volatility. It was developed by wheels builder and featured in his 1978 book new concept in technical trading system.the indicator recognise that volatility may prevent further from recognising the real trained on the Ravi and becoming too focused on the short-term price volatility instead.
How to calculate ATR?
Average true range is multiple by 13 and added to the the current trading range the sum is then divided by 14. [(ATR1*13)/14=ATR2
ATR1=previous ATR
TR=current periods trading range
ATR2=new ATR
PTR realise on the starting point because the calculations of current and all future 80ah levels is going to be affected by the level of volatility in the initial 14 periods the outcome is also going to be affected by whether those periods are quite volatile or very smooth.accuracy may be improved by calculating a TR based on an initial longer period perhaps even a 52 weeks rains instead of only 14 days.even with the longer period the volatility during that period compare to more recent level of volatility may also distort ATR.
first second problem grows from the fact that lower price securities tend to move in a narrow range than higher price securities. As a result lower price securities tend to had lower ATR and higher price securities tend to have higher ATR because the calculation is based on the point range. An alternative may be to use percentage change over the period being arranged
hyva the combinations of trading price levels of different securities with the issue of the starting point for the calculation method is a difficult indicator to rely upon for timing of decision.the study of candlestick pattern to confirm price pattern and volume is a more accurate method for measuring a price volatility.
Problems with ATR
There are two problems with ATR
The outcome varies depending on the volatility of the starting point. Second calculation is based on point range so lower-priced securities tend to have lower ATR than higher price once with larger point trades in their range.
