Running count that resets

Hi,

 

I have a data set where I want to count the number of Loss or wins in a row, but reset each time it switches to the new name like this:

Win

1
Win2
Win3
Loss1
Loss2
Win1
Win2

 

The Trade UID is the main index for this table that is unique.

Any guidance on how to do this would be great, I've tried quite a few different things and the closest I can get it to create a running count, but can't get it to reset.

 

A sample of the dataset can be found here: https://1drv.ms/u/s!Ag_sNauqdCgpg95oGmGBlk9NJrf0Uw?e=hICHI1 

 

Thanks

PQ and Excel formula are way much conciser and more straightforward,

Grouped = Table.RemoveColumns(Table.Group(Source, "PnL Text", {"ar", each Table.AddIndexColumn(_, "Streak_PQ", 1)}, 0), "PnL Text")

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is beyond their comprehension!

DAX is simple, but NOT EASY!

This worked a treat, I used the PQ version in the end. Thanks for quick help.
