There are a couple of versions and so they mostly operate the same. Fidelity recently modified them to basically operating as If/Then statements. So if you have AVYA you would write if (condition) is met (we will use last trade price for this example) "last price is $1.40 or above" THEN activate trailing stop with (condition) either a percentage or a straight amount. In our example lets say we put in 10 cents.Are there limit orders to prevent losses?
I guess that'd be a stop loss. How do you do this in Fidelity?
So it would play like this... Last trade hits $1.40 . Condition is met and the trailing stop order is now active. Stock keeps moving up to $1.60 and then retreats. Since it hit a high of $1.60 since activation it will trigger the sale at $1.50 (1.60 less the 10 cent trail you set).
It can fuck you on illiquid stocks or stocks that are really volatile where the spreads on the bid ask get wide so keep that in mind. You might trigger the sale at $1.50 but the spread might be 1.30 - 1.50 and you end up filling at 1.30 since thats the bid.
Also you can set the trail as a percentage also instead if a fixed amount and it will trigger that way.
