What does ''I open at the close'' means?

あなた have to read the book... between the lines.

There's a relationship between the "close" and the "going to die". Death is just the passage between an end and a beginning. Remember what Dumbledore 発言しました : "To the well organized mind, death is but the 次 great adventure." He saw death as a beginning, the beginning of a new adventure.

He had 与えられた the Snitch to Harry as a bequest. Obviously, he's the one that 魔法にかけられて it to "open at the close", first with the writings, and when the end is close indeed, when Harry 発言しました "I'm going to die". Saying so, Harry is indeed at the "close" of his life. Hence the Snitch opening itself to free... ah no, I won't spoil it for あなた !

Read the chapter in question, even several times and you'll see, you'll get it ! (It worked for me.)

'I open at the close' means that the snitch will open and reveal the resurection stone when Harry is about to die. The 'close' is death, as death is the closing of life. So when Harry says 'I am about to die' it opens, as he is nearing the close

never heard of it

The "close" being referred to is the end of the book and the close of the Harry Potter saga. The opening is pretty much self explanatory. JKR wants あなた to think the close is death but my explanation is better. ;)

it means it will open when he is about 2 die

I am pretty sure it means "I open when things are going wrong" like when Hagrid 発言しました that he was going to die. Therefore, I am guessing that "the close" means "the bad または the uncontrollable things."

"The Close" means:
get finished-die-poof
"I open at the close" as many of us allready said,simply means that the Snitch opens in あなた dying moment または when あなた know あなた are about to die.
Simple as anything.

It means that the Snitch will open when Harry is about to die. "The close" is considered as being the end of Harry's life.
