Grey 1 - The bands measure the SD from the MA. The MA isn't stationary, so I don't quite grasp what you mean by the first point.
I find the bands useful in describing price action relative to itself e.g. the squeeze, expansion, relative high low definitions etc.
Sure volume isn't included, and I agree that price is manipulated a lot more than most would like to believe. Thats why volume should be taken into consideration when making calls.
They are not perfect either - but what is?
To be honest, I'm not the biggest fan of TA anyway! (indicators, chart patterns such as triangles H&S etc)
I don't think that B Bands should be used on their own as entry signals, but they are very descriptive of price action when taken into consideration with other variables?
Thanks Grey1. You have a point. To be honest, I never realised there was such a thing as VWMA! I'm not a massive fan of indicators. I (like to) believe that all I need to know is on a price chart and volume clip (with Bollinger bands to give some additional description sometimes)
My charting app has around 140 indicators on it. 139 of them I never use! VWMA is not one anyway. Maybe it's time to upgrade!!
BBB, bollinger bands certainly does have use. I'm no expert on indicators and am a newbie when it comes to trading, but I use BB bands together with another indicator and so far this morning I had 15/16 ITM trades with binary trading.
Maybe older indicators are of more use than we think. Just putting that out there. Peace
