The stick sandwich is a bullish position that implies the increase in a stock, but the parameters for forming a stick sandwich are extremely strict.
A perfectly formed stick sandwich will show the stock moving upward. The bottom parts of the downward sticks show the price level that the stock will resist and stay above. You can place your order for a long-trade or a call option when the second downward stick is fully formed. Create a stop-loss order near the bottom by adding the middle part of the sandwich to the bottom of the other two parts. This should give you enough coverage if it takes extra time for the positive trend to start going.
