Overview Range % How it's calculated

[gstar1975]

Quote from The Betangel Guide on how the range% is calculated by Betangel on the Overview chart.

"Range % - Where the current price sits in the range between high and low prices. For example if the range is 3.0 – 3.6 and the current price is 3.6 the range will read 100%. Or 0% if current price is 3.0."

But it says its uses the current price.

Is that the current Back Price or Lay Price or Last Traded Price?

I have worked it out using all of these and it still isn't the same as on the overview chart.

High 12.0
Low 4.9
Range = 12 - 4.9 = 7.1
Current BACK Price = 5.2
Current LAY Price = 5.3
Current Last Traded Price LTP = 5.2

Diff CBP - Low = 5.2 - 4.9 = 0.3 (Same as LTP)
Diff CLP - Low = 5.3 - 4.9 = 0.4

Range % using CBP = 0.3/7.1 = 0.042 = 4.2% but the current Range % shows 8.57%
Range % using CLP = 0.4/7.1 = 0.056 = 5.6% but the current Range % shows 8.57%

And if you reverse the calculation if the Range was 8.57% then the "Current Price" would be:

7.1 x 0.0857 = 0.608 + (the low) 4.9 = 5.50

What I am saying is it seems the calculation is wrong. So when I am using this file Range % Value .baf file it is the same as the Overview but is different to how I am calculating which I think is the correct way to calculate the range. Does it use absolute low and high or does it only use the lowest with a minimum amount matched say £100 at the extremes to get the low and high?

ok good luck

I think it’s 100 minimum. But Dallas will know.

There’s 3 different calculations going on here,
Dallas file uses IP%, AKA (The selections book%)
The market overview uses ticks, eg. low 4.9 = 179 ticks , high 12 = 214 ticks
You’re using odds.

The highs and lows need £100 matched at the price.

Here’s a test file calculating the Range by ticks. (not fully tested)
Use the SV = R_range

RANGE (ticks).baf

That explains it thank you Dabbla!
