Many support and resistance indicators are based on picking peaks and troughs in prices over the "x" number of days to suggest that the indicator shows an appropriate support or resistance level. 

 

The trouble I have always had with these indicatoprs is that if I superimpose the indicators on top of one another they do not agree with each other so I am left with the conundrum - which one is more right? and basically,  it gets down to the assumptions made by the indicator writer when writing their code.

 

Maybe a better way, going back to my VSA routes is to introduce volume.

 

Volume is activity (where some Smart Money players have put their, or more likely their clients,' money, on the line to change the direction of the market). 

 

Volume is usually a fact of life albeit it may differwhewn reported from different  data vendors  but if you trust your data vendor then go with it.  

 

I have developed the following indicator (and show the Bullcharts code further below which is based on volume to identify the more naturally occurring support and resistance levels. 

 

For my own internal consistency, some of the parameters I used in deverloping the indicator  are the same as the parameters I used in my VSA indicator code inputs but you are free to do what ever you want with the indicator code and parameters.

 

What I am really trying to identify is what Volume multiplier times the moving average of volume brings about change of direction in a particular index or stock based on the timeframes likely to be traded.   Once you have the indicator in Bullcharts then change the multiiplier up and down to finds what you think is the key level for your index or stock.

 

It is always useful to tell a story so I will show Bullcharts chart below for the following

 

1. DJIA daily index 1929 crash and aftermath based on charts with diffent Volume indicator multiplers

2 More recent GFC Crash and aftermath todfate for CBA Bank daily bar chart

3. 15 minute chart CSL

 

I wil post charts separately

 

 

 

 

 

 

 

 

Compare the above Support and resistance levels with a multiplier of 1.35 to to a Multiplier of 2 X the moving averqage.  The higher number shows stronger support and resistance levels.

 

The way to trade might be to consider taking a trade or staying in one in the direction of the bars after a very large volume day occurs.

 

The fills are colour coded for Bullish or Bearish closes on the particular very high Volume day but this may ponly be indicative of subnsequent direction.  The  bars following the very high volume day shown the best direction until the subsequent very high volume day occurs.
