could you help me with a formula for calculating if price has reached its 5 day ATR  from previous day and display this on a chart for any day ( specifically for the london close session)

I'm not quite sure I understand the question. Price and ATR would not normally be on the same scale unless ATR is being added or subtracted from something else derived from price.

Do you mean the true range of the current trading day is greater than the 5 period average true range from yesterday?

(H - L + ABS(H - C1) + ABS(C1 - L)) / 2 > (AVGH5.1 - AVGL5.1) / 2 + (ABS(H1 - C2) + ABS(C2 - L1) + ABS(H2 - C3) + ABS(C3 - L2) + ABS(H3 - C4) + ABS(C4 - L3) + ABS(H4 - C5) + ABS(C5 - L4) + ABS(H5 - C6) + ABS(C6 - L5)) / 10

5-Period Simple Moving Average of True Range:

(AVGH5 - AVGL5) / 2 + (ABS(H - C1) + ABS(C1 - L) + ABS(H1 - C2) + ABS(C2 - L1) + ABS(H2 - C3) + ABS(C3 - L2) + ABS(H3 - C4) + ABS(C4 - L3) + ABS(H4 - C5) + ABS(C5 - L4)) / 10

Bruce this is your formula from above. 

Does the Volatility Stop use the Simple Moving Average of True Range or Exp.

 if SMA i need the above for 6-Period Simple Moving Average of True Range

IF EMA then i need 6-Period EMA of True Range

Thanks

I believe i figured out the 6 Period but you can confirm for me.

IS There a TC2000 name for Volatilily Stop (i.e On Balance Volume is OBV and Volume is V)

I am trying to write PCF where C > Volatility Stop (want to identify if by the terms of Volatility Stop we are in UpTrend or DownTrend state)  I am using 6 Period with 1 multipler.

I do know that when an UpTrend that the VS using 6 period, 1 multipler is very close to this Value

(MAXC5 - ((AVGH5 - AVGL5) / 2 + (ABS(H - C1) + ABS(C1 - L) + ABS(H1 - C2) + ABS(C2 - L1) + ABS(H2 - C3) + ABS(C3 - L2) + ABS(H3 - C4) + ABS(C4 - L3) + ABS(H4 - C5) + ABS(C5 - L4) + ABS(H5 - C6) + ABS(C6 - L5)) / 12))

and when in Downtrend is very close to this value

(MINC5 + ((AVGH5 - AVGL5) / 2 + (ABS(H - C1) + ABS(C1 - L) + ABS(H1 - C2) + ABS(C2 - L1) + ABS(H2 - C3) + ABS(C3 - L2) + ABS(H3 - C4) + ABS(C4 - L3) + ABS(H4 - C5) + ABS(C5 - L4) + ABS(H5 - C6) + ABS(C6 - L5)) / 12))

I JUST CAN'T WRAP MY HEAD AROUND HOW TO DETERMINE WHICH IS THE CASE

A little cleaner sorry

There is no built in name for the Volatility Stop and there is no way to create an Indicator Formula for the Volatility Stop which is short and fast enough to be practical or post in the forums.

The calculations are quite a bit more complicated because the extreme used to calculate the volatility stop can theoretically be any number of bars ago.
