What if the stock opens below the Ctabs "sell" target price?

If the stock opens below $30, you may want to take the profit right away before witnessing the possible outcomes at the end of the trading day.
   (A) The stock closes with an up candle.
   (B) The stock closes with a down candle.

For (A), you should not have carried out the "sell" action and you may have taken profit too soon thereby "leaving money on the table".

For (B), you should have carried out the "sell" action and you did plus you took profit at a more profitable price point relative to the closing price.

Those are the options and your action is largely dependent on your trading philosophy and style. A more conservative style would suggest taking profits when you can. A more aggressive style would suggest waiting for more profits (of course being subject to continued risk).
