I use a bracket when I order of 2 tick profit and 4 tick trail stop. Most of my trades are market orders so the bracket is actually 1 up and 5 down. The market order almost always ticks up one therefore the trailer tightens by one so the bracket is actually 1 up and 4 down. My algorythm expects a trade of less than 2 minutes. Last week my trade was much less which means a higher win rate.
As far as your system goes, the money management is called geometric progression and in theory doomed. If you double up and double up, sooner or later you will get stomped out from lack of margin. If you had unlimited funds and the ability to place unlimited amounts of orders, the chances of you busting may not happen in a lifetime. So, the less you start with in your margin account, the sooner you will meet doom. My understanding of geometric progression and how it applies here.
