ROKU has an incomplete bottom ahead of its earnings report later this week. The technical patterns don't indicate a bad report, just not a great one.
There is some accumulation and a shift of sentiment around the lows of the bottom formation, which are likely to provide support. It is unlikely that this stock would drop further than the Dark Pool Buy Zone unless it has a bad report.
The company has struggled with Market Saturation for a while. Some strategic partnerships recently and in the future may be what the stock needs to stabilize here to eventually begin the next uptrend.
