Confused with Trailing Stops

 

I'm confused with how Trailing Stops work can someone help explain? I noticed I have to input a Stop Loss first before I could set a Trailing Stop

Sorry noob question

Lets say the situation is as follow

Did a BUY for USD/JPY @ 110.00

Stop Loss @ -40 pips

Trailing Stop @ 20 pips

Help?

 

it will keep your profit 20 pips far from current profit

ie. when you've got the profit more than 20 , the trailing stop will awaken to work .. like...now the price is 110.25 = u got 25 pips profit then trailing stop will set a new stop-loss at 110.05
