PJ, it was good to see you this morning. To answer your question about exit signals. I have quite a few, ASCT lighting up, EMA crossing T3, Parabolic SAR on 5, 15, 30, 1hr time frames. For example, if market is trending smoothly and uniformly for two or more days, I would exit when ASCT lights up on a 1hr chart and that's what I did with the downtrend of GBP and EUR from last Friday (I also look at the daily and weekly chart to get a general idea of where price is heading when a day trade becomes a swing trade). For something like a 100pip spike, I might exit if ASCT lights up on a 5min chart or I might exit because I was too excited,

. Usually I'll use Parabolic Sar, if I'm not around to monitor the market.
I'm not currently trading my modified version of Mark3's system (which is on page 16 if anyone cares to look). But I am tracking it in both the EUR and US session, and keeping an eye on other people's development of the system. I would love to trade an emotion-free mechanical system, but for now, I'm looking at different things - Fib. Lines, Pivot Points, candle stick and chart patterns for scalping. So far, it's as good as a coin toss, which might not be a bad thing if I have my risk and money managment right. For the regular day/swing trades, I'm also looking for trends in RSI, STOCH and ADX. Let say all three of these indicators were trending up, breaks the halfway mark to indicate pressure on the buy side (for ADX, it would indicate increasing momentum), at the same time ASCT, Heiken, EMA's & T3 are all confirmed for buy, whether price has moved 30pips ahead or is already 40pips ahead, I would probably pull the trigger.
