Before I depart to the world of anathaesia tomorrow, I thought that it might be an idea to share a little of my experience, of Corrie testing, over the months. This may be particularly useful for those who are new to the thread.
One of the key elements in using Corrie, successfully, is to find a setting that produces fairly accurate trading signals. I don't believe that there is an ultimate setting, for the simple reason that the forex market is constantly changing. We are in a period of fairly low volatility, compared to 18 months ago. In addition to this, preferred tf, individual risk appetite and time available to screen watch will vary from person to person.
In my opinion, the biggest obstacle to Corrie is MT4's auto scaling function. Before migrating to MT4, I used VT Trader which allowed the user to set the scale and move the chart vertically up or down, via use of a slider bar. Why does this matter?
I would think that many of us have Corrie in Indicator Window 1; all well and good so far. The anomaly occurs when you reduce or increase the amount of chart real estate that Corrie takes up.
If I set up to Corrie to cover 80-90% of the chart, I will have small candlesticks/bars that appear as a meaningless flat pattern and a vertical scale that might be 20-50 pip increments. I have found that the best format is for Corrie to take up 40% of the chart space which, doesn't throw MT4's autoscaling off too much. However, there will still be slight pattern differences between the 80-90% and the 40% Corries but, not enough to be crucial. I'm hoping that the new MT5 might include a proper scale fix and a slider bar.
My set up is based on 5 min tf+ with a 34/3 setting. I have G8 Corrie attached to all individual pairs (40% of chart space) and a separate page with Corrie occupying 80-90% of the chart, in order to get a magnified look at the action. If I had a larger account, I would be quite happy trading Corrie off the daily tf. No screen watching all day; just set TP and SL, at the end of the day, and off to play golf the next morning
