Sequences of positive and negative numbers in array

I have a column with 1000 cells and its a random mix of positive and negative numbers.

What I want to do is to create a formula that answers the statements below in 4 individual cells:

* How long is the most negative number sequence (How many straight losses)

* What is the sum of that sequence of losses (Total down streak)

* How long in the most positive number sequence (How many straight wins)

* What is the sum of that sequence of winnings (Total up swing)

I also would like to answer the following:

* What is the average downswing / upswing in sequence number
* What is the average downswing / upswing summorized

Been googling around, think i need to create array using FREQUENCE but I really cant grasp how to implement!

Thankful for help!
