Back-testing: Graph reading, Steep Drop at "Close at Stop"

Hello Gurus,
Appreciate if you would shed some light on these queries. Thanks.
Q1: There is a steep drop at the end of back-testing, do you count it as part of the back test?
What's its actual implication to draw-down. In real life, one would not pull out of the trade abruptly.
As per this graph, does this EA have good potential? Do I need to be prepared for a huge drop like what it is at the end of the back-testing.

Q2: (this is from another EA). At the beginning, the Equity is higher than the balance, something happened around order 920+, equity started to drop drastically.
From the result table, there is a huge gap, where the EA was just hovering over the trade. In live trading, how should one be prepared for a huge drop in equity.
Is there a way to find out what actually happened during the gap? How to find out what is the magnitude of the drop in Equity?
In live trading, since the Balance is ascending, despite the trailing Equity, should I or can I wait for Equity to catch up and reap the profit?
Thank you very much

The big drop at the end is just the tester closing all trades left at the end of the backtest. Nothing related to the EA strategy itself.

Thanks for the explanation for Q1.
Any thoughts on Q2?

If within the backtest you have some opened orders in a global loss, the equity (floating balance including opened orders) is below the balance.

Hi Trading Guru,
I hope you would please shade some light on this;
If Absolute drawdown is defined as "The largest monetary loss that is below the initial deposit value".
The figures indicate a $202 drawdown from initial deposit of $1000, but the graph doesn't show a decline in balance nor in equity below $800.
Shall I take the indication from the figures or the graph. It has been bugging me for a while.

Thank you

I have this problem currently. The EA does amazing for a couple of months and then all of a sudden this sudden drop. Any idea what's causing this? Did you fix it?

But why is the EA closing these trades? For example, I ran 07-23-2017 - 07-23-2018, and the strategy tester was going well until Dec 28, 2017 where this sudden drop happens. I've went back and it was normal market conditions, so I have 0 clue why this is happening.
