Thank you,
I am not sure if this is what you are getting at, but this is beginning to start the thought processes off for me.
I think you are not just talking about scaling in and out of a trade but something more profound.
Risk reward is a constant and on going assessment it is not a black and white yes or no question (in the same way it is tempting to look at an individual trade) but it has various degrees.
So if an open trade has on going various degrees of risk reward I should be making sure I am the position to reflect this with trade size and start to seriously see myself as managing money rather than individual trades.
