Breakaway gap is best supported if we can see a chart pattern before the actual breakout. In case of GMA7 its looks like there is a symmetrical triangle but its not 100% accurate. There are guidelines to follow when drawing a symmetrical triangle and in this case it SOMEWHAT fits. Still, I would say there is a bullish sentiment surrounding GMA7/GMAP not only technically but about the mergin news of Manny Pangilinan’s TV5 and GMA 7.
If the triangle will be considered symmetrical then there is no way, at least in the immediate future, that the gap will be filled. Instead, the price will shoot up and you will be left behind if you don’t get in early.
But if this is the case of common gap then, then you don’t have to get in early because the gap will be filled first and no one knows when will be the next uptrend.
