What is SSL/HSL:
SSL is short for soft stop loss, wait for the mentioned time frame of the candle to close below X price whilst taking a loss. Used occasionally to avoid getting wicked out of positions. HSL is short for hard stop, the usual kind SL you use.
What is DCA:
DCA is short for dollar cost averaging a position. You can add margin into a trade that's underwater and the added margin makes the entry come closer to the CMP. If done in a risk managed way, it is very helpful.
What is CMP:
Short for current market price, enter the trade now.
What is SL BE:
Short for StopLoss BreakEven. It means to put the SL at your entry after TP1 gets hit. Even if price reverses after TP1 you won't experience any loss as you get stopped at your entry.
