Snapchat $SNAP has been falling since shooting up to $21 a share in early February. As share price tags $14, SNAP is testing a key support.SNAP Daily Chart(click to enlarge)Support:- The daily chart shows a choppy market, but one that has flattened the bearish price action in 2017. - However, the bearish momentum since February's high is strong. - Price action also shows bearish bias as the latest rally was rejected at $16.00, holding price under the 200-, 100-, and 50-day simple moving averages (SMAs). - A break below $13.25 could open up a bearish push to $11.50, and even the $10.00 psychological level.- A hold above $16.00 on the other hand establishes a price bottom, and at least puts the $21.00 high in sight again.
