Hi:

What is the definition of net vs absolute difference in the following code?

Thanks,

Jeff

If you mean the Net Difference then:

Static Basis As Single 
If isFirstBar Then 
    Basis = Single.NaN
Else If Price.DateValue.DayOfYear <> Price.DateValue(1).DayOfYear Then 
    Basis = Price.Last 
End If 
Plot = Price.Last - Basis

If you mean the Absolute Difference then:

'|****************************************************************** 
'|*** StockFinder RealCode Indicator - Version 5.0 www.worden.com 
'|*** Copy and paste this header and code into StockFinder ********* 
'|*** Indicator:Jeff Open vs Close Absolute
'|****************************************************************** 
Static Basis As Single 
If isFirstBar Then 
    Basis = Single.NaN
Else If Price.DateValue.DayOfYear <> Price.DateValue(1).DayOfYear Then 
    Basis = Price.Last 
End If 
Plot = System.Math.Abs(Price.Last - Basis)

The net difference between the open and the current price can be positive, negative or zero. For example, if the open (Basis) is $100 and the current price (Price.Last) is $99, then Price.Last - Basis would be -1 but if the open had been $98 instead, then Price.Last - Basis would be 1.

The absolute difference only considers the magnitude of the difference and does not care if the result is positive or negative. It converts negative numbers into positive numbers and leaves everything else unchanged. So in the example above the absolute difference would be 1 both when the open was $100 and when the open was $98.

Hi Bruce,    I was sent an email  answer however, I asked a different question.   I am in need of this:  After 4 or more down days a Gravestone doji candle appears and the stock closes above  $1.00. Or a Dragonfly doji candle appears   or a long legged hammer appear. Or would  a formula for  just any doji appearing  be doable.  (the Gravestone/dragonfly/longlegged hammer would be best ) Thank You & my fingers are crossed.      Arnie

What follows is the answer I already gave in the Not a True Gap topic.

So a Dragonfly Doji where a True Doji with the open and close being exactly equal happens in the top third of the candle could be written as:

H - C < (H - L) / 3 AND O = C AND C > 1 AND C1 < C2 AND C2 < C3 AND C3 < C4 AND C4 < C5

A Gravestone Doji where a True Doji with the open and close being exactly equal happens in the bottow third of the candle could be written as:

C - L < (H - L) / 3 AND O = C AND C > 1 AND C1 < C2 AND C2 < C3 AND C3 < C4 AND C4 < C5

A Hammer where both the open and close are in the top third of the candle could be written as:

H - O < (H - L) / 3 AND H - C < (H - L) / 3 AND C > 1 AND C1 < C2 AND C2 < C3 AND C3 < C4 AND C4 < C5

And an Inverted Hammer where both the open and close are in the bottom third of the candle could be written as:

O - L < (H - L) / 3 AND C - L < (H - L) / 3 AND C > 1 AND C1 < C2 AND C2 < C3 AND C3 < C4 AND C4 < C5

None of these formulas have any restrictions on the size of the overall size of the current candle. If your definitions are different, then the formulas would need to be different as well.

For example, the formulas check for four down days in a row using just closing prices. If you define a down day as the close being below the open, this would need to change in the formula. If you want the hammer formulas to explicitly exclude dojis, you would need to specify that in the formula. If you want to use something other than the top and bottom third of the candle for the body locations, that would need to be changed.
