Polygon is moving alongside an uptrend since October 19. The MTCUSD tried three times to cross the resistance at 0.8600, but failed. Its prices have finally formed a Bearish engulfing candlestick pattern and went into correction. So, we may expect a further downside correction. I believe, it would be interesting to consider short trades from 0.8370-0.8420 with a target at 0.7870, the low of November 9. The stop-loss could be set at 0.8620.
