I have a style where (for long positions) I put a stop limit triggered if the stock goes 5% below my purchase price with a limit 6% below the purchase price. If the stock goes above 6% of my purchase price I set a stop limit triggered if the stock goes to 75% of the highest profit I could have taken since holding the stock with a limit of 70% of that profit. I do similarly for shorts. I find this quite tedious to do by hand. Which brokers have systems which would allow me to set this up or do some reasonable substitute, automatically, when I enter a position? Thanks.
