Next I wanted to try it on a basket of currencies as currencies tend to trend more than the ES. Here are the results:. These results definitely look better. Additionally, the Long trades performed slightly better than Short trades, making the edge even greater. Entry Conditions: If we have 2 consecutive bars close outside of one of bands, enter a trade in the direction of the breakout.

Here we see that the results are better than with just a single close outside the bands.

There are fewer trades, as we would expect with tighter entry criteria. Again that could be due to the market type over the period, but additional study is required to determine if there is a correlation.

How to Measure Trading Success

I also tested the strategy against the same basket of ETFs. So it appear that for some instruments, this entry strategy certainly would be exploring in detail more. Additional study is needed to determine if there is a correlation between market type and the discrepancy between long and short trades. However, with a good exit strategy, this entry has the potential of offering an edge for your trading.

The use of standard deviation as a standalone indicator is somewhat limited though, and there are more applications when using it as building block in combination with other tools. For example, standard deviation is used as a key part when constructing the Bollinger Bands , probably the most famous type of volatility channel indicator. With this indicator, a moving average acts as a centre-line and then volatility channels — the Bollinger Bands — are plotted a number of standard deviations above and below.

John Bollinger, who invented the indicator, suggested that when bands narrow, there is a high chance of a subsequent spike in volatility. Trend-following traders also use the bands as a breakout signal. There are plenty of other ways in which you could use standard deviation in combination with other indicators. For example, you could use a trend-confirming tool, such as a moving average, or several moving averages in combination with each other e.

Using Bollinger Bands to Gauge Trends
