      for patterns. The systems work fine in EOD but I observed on the 
      RT charts that i often miss locking in some really nice profits 
      that fade before I exit. So i want to code in Trailing stops that 
      activate at a certain profit and than exit when the price drops back a 
      bit. For example, if my profits reaches 2% during the first two hours 
      of the trade, then i want to activate a Stop and exit when my profits 
      drop back to 1.5%. ApplyStops cannot be used in very short-term (1-3 days) 
      trading because on the day of exit it is unknown which came first, the 
      High or the Low, or with profit stops, how many dips there were during the 
      day that would have terminated the trade. RT data is needed to develop 
      proper stops. limits, etc. with the short trades i use.

      to reduce my exposure by 50% if I managed to get out based on profits 
      instead of timing. I would prefer overall less profits if it came with 
      less exposure. Also, the strength of signals fades pretty fast... have you 
      ever tested your n-Bar profits? i.e. profits made on the 1st, 
      2nd and 3rd day? You can vary the entry delay and use n-Bar stops to limit 
      the trade duration, that way you can "isolated" single days (profits) of 
      your trade. For me, typical profit distributions might be 65% 25% 10% 
      for a system with an average of 3-bar trades. So the first day obviously 
      has the greatest profit potential at the least exposure. IMHO, short term 
      signals have a limited life-time: after a certain number of days you are 
      just hoping to get lucky :-) knowing your n-Bar profits may help you 
      decide whether it is worth it (risk) to stay in a trade or 
      not.

          Real-Time Trading System Examples
          
          Would 
          anybody have some example code for Real Time trading 
          systems? I have considerable trouble converting EOD 
          systems to RT data - tried too many ways to mention but always 
          hit a snag at some advanced point. My problem areas 
          are:
          <SPAN 
          class=937152314-09042004> 
          <SPAN 
          class=937152314-09042004>1) Converting or duplicating EOD 
          signals to RT, I need this because EOD data prices are 
          more accurate than those I get from RT 
          sources.
          2) Running 
          the basic EOD system in RT, i.e. reproduce EOD signals in 
          RT. I want this as a verification stage before trying to enhance 
          the system with RT data
          3) Custom 
          coding Profit targets, Limit Prices and Stops.
          4) 
          Optimizing entry points by using Pre/after hours trading and/or using 
          delayed/early entries and exits.
          5) Showing 
          EOD Arrows (derived from EOD data, not from RT data) on my minute 
          charts. 
          <SPAN 
          class=937152314-09042004> 
          If anybody 
          has example code or reference URLs to share that would be much 
          appreciated. 
          <SPAN 
          class=937152314-09042004> 
          Also, i am 
          beginning to wonder how many subscribers, if any, have 
          actually solved the above problems. If you have done 
          so perhaps you can share this simple fact (no code 
          needed), knowing that it has been done successfully is a 
          great motivator :-)
