I'd just written a very long and detailed post. Then timed out. Not going to write it all again, but the main points:

Armstrong's timing model is subjective even when he says it is objective.

If you're following even his long term calls, you still are using Socrates and not his fundamental analysis, because that would be subjective.

Armstrong's technical analysis seems to work and he sometimes times the corrections but sometimes false positives.

There's a new post. If someone wants to post it, we can see if the Dow is a temp high or not based on his call if that's what the title refers to.

There are certain high probability trades in the market. Use alignment and confluence of price levels. I got this strategy from Armstrong. It works.

If Armstrong is a big shot, other big shots should have mentioned him. Any Paul Tudor Jones, John Paulson, etc say anything?

Armstrong refers to himself on his site when he is in the news- its usually the single 'pi in the sky' news article.

An objective third party is required to translate Armstrong's calls so no one can say he was right or not. That third party is your trading account.
