Around a month ago I made an analysis on MATIC and the channel it was trading in.
With MATIC seeing a strong reversal from the top resistance of the channel, there's a decent chance for the price to reverse from there. In case of BTC weakness, I'm looking at the yellow area for a potential rebound from the support area. Be aware that this is not a short signal, since we're looking for a bounce from the support.
In case of a bullish break out, this trade would naturally be invalidated.
