Hello Mr Valley,
Firstly, Thanks for taking the time to help.
The actual Buy Condition you posted "Buynow = Cross(IndA, IndB)"
would be correct and this would be the LAST bar in the pattern.
However, to confirm the actual pattern, I would also need to confirm:
1. When the first bar in the pattern appeared ie. The previous time
that IndA > IndB.
2. that IndA < IndB occurred on ALL the bars between the first & last
bars,
I'll give a couple of examples of what would be classed as a
confirmed pattern.
Example 1:
Bar 1 = IndA > IndB
Bar 2 = IndA < IndB
Bar 3 = IndA < IndB
Bar 4 = IndA < IndB
Bar 5 = IndA > IndB
Pattern Length = 5
Example 2:
Bar 1 = IndA > IndB
Bar 2 = IndA < IndB
Bar 3 = IndA < IndB
Bar 4 = IndA < IndB
Bar 5 = IndA < IndB
Bar 6 = IndA < IndB
Bar 7 = IndA > IndB
Pattern Length = 7
Hopefully, this makes sense.
I'll just like to add that all the above is just for the BUY
Condition. I don't want to worry about Sell Conditions at the moment
as I need to get my head round this first :-)
Thanks,
Chorlton
