Your having a system almost looks like a figment of your imagination.....
You may hold on for a few days and maybe even make money on this trade, but a system that keeps you in a trade that is against the trend for such a long time, is not a system at all.
All the best for your gambling.
Hope you make money on this trade, and realise the importance of a REAL system, and not just a system that exists only in your imagination.
PS: I am no authority on trading systems, but do know that if the market goes 300 points against you, and you are still stuck in the loosing trade, its not a system at all, just loosely bound statements pinned on hope.
PLEASE PLEASE dont take this as an offensive against you. I again re-iterate that I am not an authority on trading systems.
