[amibroker] Re: Dimitris... QQQ Trendline Support again

I don't think I see anything you miss.

For now I am looking at this as a discretionary long position based
purely upon my subjective belief in trendline support. If I'm wrong
I'll get stopped out early with little damage.

But with the help of your afl code efforts, I shall look at the
mechanical side of trading trendlines, and I'll either confirm or
dispell my subjective leanings.

Do I gather from your comment that you are leaning toward believing
that support will be broken, and if so, why?
