Gesture for wiping instead of swiping

With the code underneath I manage to detect swiping from left to right and right to left.
However, what I want is to detect a wiping gesture.
So, the movement is left to right to left to right without releasing your finger to the screen (almost like clearing the screen with a rubbing movement or a better example: the swype function on the keyboard of samsung device).

The problem is that I need to release my finger to detect swiping to left or to right.
I already used a counter for swiping. If you swipe 5 times, something is activated.

How can I solve this?

Code:

---

Multitouch.inputMode = MultitouchInputMode.GESTURE;

var swipeCounter:Number = 0;

stage.addEventListener(TransformGestureEvent.GESTURE_SWIPE, onSwipe);
stage.addEventListener(Event.ENTER_FRAME, enterFrameHandler);

function onSwipe(e:TransformGestureEvent):void
{
        if (e.offsetX == 1)
        {
                trace("User swiped towards right");
                swipeCounter++;
        }
        if (e.offsetX == -1)
        {
                trace("User swiped towards left");
                swipeCounter++;
        }
}

function enterFrameHandler(event:Event):void {
        count.text = swipeCounter.toString();
        if (swipeCounter == 5) {
                swipeStatus.text = "geswiped";
                trace("Swiped");
                swipeCounter = 0;
        }

}
