BTC is doing higher low as you can see on the picture. If you square the price range (Gann square) from min to max you can see that BTC has touched three times 1x1 and the price has rosen each time confirming that up-trend is still intact. As you can see there is a positive divergence on RSI indicator too (from the min touched in september 2017). This picture is published only for educational purpose, you can invest at your own risk.
