Could someone tell me whether it is possible to initiate a stop loss if a share price drops by 5% at any time, not just below what was paid? Example: If I paid $10 a share and it was now $20 a share is it possible to have an automatic sell in place if it drops to $19 (5%) and if the price keeps going up can that same sell option stay with the share so it sells whenever it drops by 5%? I can't see anywhere to set this up on my Comsec account. I've bought shares at good prices for a long time but have never been good at knowing when to sell and thought this might be a good way to improve my returns. Any help or comments much appreciated.
