As of now, I don't think Daniel 9 has anything to do with the anti-Christ, I've looked and looked at this passage and still remain undecided. So what I typically do is get away from it and return and study it again later. Verse 25 is key to understanding the rest.
Hal, take a look at these verses....
Deuteronomy 31:
9 And Moses wrote this law, and delivered it unto the priests the sons of Levi, which bare the ark of the covenant of the Lord, and unto all the elders of Israel.
10 And Moses commanded them, saying, At the end of every
seven years, in the solemnity of the year of release, in the feast of tabernacles,
11 When all Israel is come to appear before the Lord thy God in the place which he shall choose,
thou shalt read this law before all Israel in their hearing.
12 Gather the people together, men and women, and children, and thy stranger that is within thy gates, that they may hear, and that they may learn, and fear the Lord your God, and observe to do all the words of this law:
13
And that their children, which have not known any thing, may hear, and learn to fear the Lord your God, as long as ye live in the land whither ye go over Jordan to possess it.

The leader(s) of Israel are responsible, on a seven year cycle, to do what Moses did, give a big speech that God gave the nation of Israel, the land of Israel as their forever. What Moses did in making the speech in Deuteronomy 31 to the nation of Israel, was essentially confirming the Mt. Sinai covenant.
That is what the person in Daniel 9:27 will do, as the Antichrist, crowned King of Israel, to begin the seven years.
In Revelation 6, the rider on the white horse is given a crown, at the beginning of the 7 years. (Revelation 6-19 is structured, the different chapters, on the 7 years, or the second half of the seven years, depending on the chapter(s) ). That crown is the person being crowned the King of Israel (illegitimate).
Deuteronomy 31:10 = Daniel 9:27 = Revelation 6, the seals - as the 7 years.
And furthermore.
Deuteronomy 31:10 = Ezekiel 39:9 = Daniel 9:27 = Revelation 6, the seals - as the 7 years.
