I have never seen parishioners in the GOC-AB Kallinikos parishes do any Greek dancing or hold a parish Greek festival where Greek dancing is done out under the stars at night, so is traditional Greek or ethnic dancing forbidden in the TOCs?
In World Orthodoxy, I know that Antiochian and Greek Orthodox Priests and Deacons have been instructed by their Bishops that they should not go to dance clubs or participate in ethnic dancing with parishioners. Although the clergy of the local Greek parish do start the parish festivities at the Anastasi dinner by dancing with the altar servers, these clergy members leave shortly after the dinner and dessert have been served while the parishioners remain until dawn to celebrate the Resurrection.
