Commander in Pips: There is one last indicator that could be used, but it has a lot of limitations - ATR – Average True Range. Its limitation links with the fact that it estimates average daily range for recent N periods. So, this range could be applicable only for 1 single trading day following after the current day. Here is an example: Chart #4 | EUR/USD Daily and ATR (21) You can see that at the moment of entry ATR tells us that the average daily range for past 21 periods is about 200 pips. So, it is unlikely that on the next day market will move more than 200 pips as to the upside as to the downside from previous close price – that has happened. But on the next day the lower border easily was broken. The reason is that this range should be counted from the most recent close bar, but not extended in the future as with Historical Volatility. ATR is very useful with different application that we’ve discussed in Charter 20. But it is not very suitable for placing stop order. Maybe those who trade intraday will find them useful, since they will get daily range by ATR value. If the market will approach upper border – they could try to sell, lower border – to buy. Pipruit: Well, personally I like Detrended oscillator and Historical volatility most of all. Commander in Pips: That is my choice also. P.S.
