We observed a "morning star" last time we looked at the stock chart of Trinseo (TSE). We note that the candlestick signal suggested a bullish attempt to follow. The 5/10 session validated this forecast, but we have to quickly turn attention to a potential resistance.TSE Daily Chart(click to enlarge)Support:- The bullish reversal signal came as price tagged a couple key support factors. 1) A rising tendline and 2) the 200-day simple moving average (SMA).- The market found support but didn't really take off until the 5/10 session. - Still, the fact that the market respected these key support factors suggests TSE might be on a bullish continuation.Resistance:- If price extends another session or two, TSE will probably find resistance around 66.00, near the 100-day simple moving average (SMA), and a falling resistance.- A break above 66.00 would be another sign of bullish continuation.
