Let's assume a Bullish pattern. A pattern has the legs XA, AB, BC and CD. If it completes, meaning it has all 4 legs and a D point, it will Buy.
But since HT ULTIMATE trades from the C point towards the D point already it says EMERGING, meaning it is not completed and has no 4th leg or D point yet. So for an EMERGING Bullish pattern it (may) Sell from the C point towards the D point. And once the pattern completes, it will say Bullish Pattern and will Buy.
Early years are totally irrelevant. It was a completely different market back then. We optimized the EA for current market conditions on 99.9% accurate tick data , more particular from 2013 to now. (And no, this is not curve-fitting) The fact that back test results for 2017, even on less accurate data, matches the live forward test, only confirms that we did a good job with optimizing the EA.
