Tough Winning Streak Formula

[Autonomous]

This is my first post on MrExcel and I really need a hand... I have a multi team game log where the dates are out of order and the data doesn't contain who played who so each team must be handled independently. I'm trying to figure out win streaks and current streaks "for each" team (Should I be writing VBA instead?) but my arrays aren't working properly. Any help would be appreciated!

	A	B	C	D	E
1	3 Teams	Date	Result	Max Win Streak	Current Streak
2	Red	1/20/2019	Win
3	Red	1/21/2019	Win
4	Red	4/20/2019	Loss
5	Blue	1/10/2019	Loss
6	Blue	1/2/2019	Win
7	Blue	1/4/2019	Win
8	Blue	1/9/2019	Win
9	Red	3/20/2019	Win
10	Red	1/6/2019	Win
11	Red	1/7/2019	Win
12	Green	1/15/2019	Loss
13	Red	1/22/2019	Win
14	Green	2/13/2019	Win
15	Blue	1/3/2019	Loss
16	Green	1/14/2019	Loss

Maybe something like this

That did the trick! My problem was I forgot the $ symbols in my ranges thanks. I also converted everything to named ranges to make it tidy. Arrays can be pretty heavy with a larger data set any tips on better performance with arrays other than limiting the range to exact values and not the entire column?

The most important thing is to limit the ranges - never use whole columns. But if the size of your data is huge the performance may not be good. Just testing to see ...
