Ferry, a 20-year-old midfielder, has yet to play in the league for his parent club this season, but has had three outings in the Football League Trophy.
He came through the youth system at Brentford before joining Stevenage and has had loan spells at both Wycombe and Welling during the last two years.
Speaking to the Stevenage club website after he joined them in the summer, Ferry said: “I get around the pitch, I am a good passer and I am a dynamic player.
“I am buzzing. I just want to get focused for next season and try to do well.”
Ferry goes straight into the squad for the FA Trophy game at home to Barrow tomorrow.
