I ABOLUTELY love Amibroker, but, I should admit that Tomasz really does disservice to his own product to not responding (as a matter of fact, AT ALL) with at least draft of some working example regarding the notorious AD-NYSE-NYSE-IND issue (and similar ones), for lamers. I know for sure how many of them were so pissed off, that they totally dumped the software. The scary thing for them was the realization of the fact that they don't have any live example how to deal with similar problem(s) in the future. Majority of them is able to tweak some ready-made script, but they usually spend more time trading than writing scripts. For them, it was the clear indicator that they are totally on their own if something like this comes up in the future.
It would take 15sec of Tomasz time to accomplish, and now it already took thousand dollars out of his own pocket. no doubt about it.
so, don't be surprised why not so many traders use and know this actually brilliant and capable product (Amibroker).
Also, I was not surprised that Tomasz did not continue something in the lines of PatternExplorer (cool plugin for Amibroker), and why the other plugin (initially discussed in the past), AlphOmega Elliott Wave (existing for MetaStock) never appears in Amibroker. No royalties, and no any additional cash flow generator for Tomasz, less fun for his users, and no money to support/extend the POSSIBLE team of developers (if only Tomasz believes that he is ethernal -- even Steve Jobs has a team, doh

).
Look, for example, at the unstable, amaterish (so far) button trading, autotrading scripts proliferating all around Amibroker right now. Ppl are desperatily trying to do something with product that it never intended to be.
In my opinion, such things should be added on the level of inner code. Yes, it's rather difficult, critical and time consuming process. Nevertheless, many believe that Amibroker should include features of trade terminal, too. It's all about priorities.
But it's difficult to be a single developer and marketing genius in total package procurement.
It's much easier to be under some false (IMHO) pretense that Amibroker takes totally different niche in the market than all other products.
At least, many active users disagree, I'm sure.

TWS does not display the data, but it is available using the API. Put NYSE:$AD-NYSE as a symbol into QuoteTracker and you will see the AD line as the ratio of advancers to decliners.
