What are the traditional prayers to end the Rosary with?
1)
Hail, Holy Queen, Mother of Mercy,
our Life, our Sweetness, and our Hope.
To Thee do we cry, poor banished children of Eve.
To Thee do we send up our sighs mourning
and weeping in this valley of tears.
Turn then, most gracious Advocate,
Thine Eyes of Mercy toward us,
and after this our exile show us the
Blessed Fruit of thy Womb, Jesus.
O clement, O loving, O sweet Virgin Mary.
Pray for us O Holy Mother of God
That we may be made worthy of the promises of Christ.
2)
O God, Whose only - begotten Son by His life, death, and resurrection, has purchased for us the rewards of eternal life; grant, we beseech Thee, that meditating upon these mysteries of the Most Holy Rosary of the Blessed Virgin Mary, we may imitate what they contain and obtain what they promise, through the same Christ, our Lord. Amen.
I don't know if you, yourself, say any prayers after each Glory Be, but there is the Fatima prayer, if you're interested:
O my Jesus, forgive us our sins, save us from the fires of Hell: lead all souls to Heaven especially those in most need of thy mercy.
But having myself, been exposed to two versions of it, I combined them and I personally say
O my Jesus, forgive us our sins, save us from the fires of Hell:
have mercy on the souls in Purgatory, especially the most abandoned and lead all souls to Heaven especially those in most need of thy mercy.
You're free to do whatever you want though, there is no set rule for any of this.
Sometimes I'll include the Miraculous Medal prayer:
O Mary, conceived without sin, pray for us who have recourse to thee.
