Set Profit Target in Points or Ticks instead of Dollars

I would like to be able to set my profit and loss targets based on points as opposed to dollars.

When I size up or down, the target dollar amount changes drastically; however, in terms of points (or ticks) my target and stop loss typically remains constant.

This is especially helpful for anyone trading the open, when price changes rapidly.

The way it is set up now, I have to take the same size or set my bracket orders manually, which can be costly when trading the open.

Not to get greedy but in a perfect world, I would love to be able to set multiple profit targets based on points or ticks.

I would like to dump 50% (or x%) of my position at (x) points profit and the other half (or third or whatever) at a higher pre-set target.
