What does cumulative P&L in streak represent?

General

For example:

I shorted 10 shares at 176.45, but price rose to 176.60. Hence I should go into loss, but Streak cumulative p&l shows it as profit (it is in Red but no minus sign). Here is the table:

23 - Oct - 2018, 10:29:00 AM TATAMOTORS NSE SELL -10 174.45 4.45 EN
23 - Oct - 2018, 10:32:00 AM TATAMOTORS NSE BUY 10 174.60 2.68 EX

(here, 4.45 and 2.68 is cumulative P&L)

Sometimes Streak shows -sign in front of p&l. Like:

23 - Oct - 2018, 11:18:00 AM TATAMOTORS NSE SELL -10 173.95 1.99 EN
23 - Oct - 2018, 11:25:00 AM TATAMOTORS NSE BUY 10 174.15 -0.28 EX

When does Streak use minus sign and why isn’t p&l negative in first example?

Also, when streak shows final returns are they calculated using funds at the end of test?

Cumulative P&L is the the sum of the accrued PNL for every trade.
-(minus) or Negative number means that your net(cumulative) PNL has gone into loss so much that its will take always from you principle capital being used for trading.
If cumulative P&L increases, this means you had a profitable trade, and if it decreases, then you had a loss making trade.
In you first example, you cumulative P&L decreased by the amount you lost in that single trade.

Hope this helps.

Thanks
