Regarding the neat entry system, I have used it for a long time. However, with the stochastics exit, I found it gets you out too soon if the pair goes on a tear. As far as exits, and I have been looking into this lately, Van Tharp says use 3 times ATR (20) as a base line trail stop. You would be still out of the GBP trade, but if it had gone on, and I have seen it, you would have much more in the bag than 320 pts.
If you look at the signal for EUR on Feb 15th or so, and use the trailing stop of about 300pts (more or less 3x the ATR20 of 100pts) you would be out yesterday with about 750 pts in your vacation fund.
I love this system, but am looking at ways to extend the time in the trade and also to find out when the trend has changed so I can enter when the 150 is flat or near flat.
Another thing to look at is a RSI/ Stoch divergence when it is a trade near the 150 line. Divergence itself is not an entry signal, but a leading indicator that when coupled with your entry signal can certainly help with the probabilities.
I have been working with another trend following system for the last year or so, but I plan to come back to the Neat Entry as a system with Toyota-like reliability.
