I have just started looking at modifying the settings on some of the indicators I use. Depending on what I am looking at. For example: have a second bollinger at 1st standard deviation, or trying different settings for macd or stochastics. But the truth is I am not really sure that I know what I am doing. Can anyone recommend a source that explains the indicators beyond the basics, so I can learn to make adjustments to the defaults which might yield improved results. Thanks
