I see the point, however there are some ethical concerns to publish data available only via a subscription basis. However I can tell you my business case, that I think is easily replicable:
The Plus Membership costs 55$ per month and with this level I can purchase any detailed report for 2 credits. 10 Credits costs 27 USD, thus a detailed report costs 5.4 USD. You will need the Detailed report to get the reversals (Arrays are not included, however turning points with monthly accuracy are mentioned together with a variety of support /resistance levels). Credits can get cheaper if purchased via bulk, but for me the 27 USD is a reasonable investment. And yes, I traded such reversals (with exception of yesterday, bad decision to wait till today, would have been a profit simply over night)
Depending on the charts, it may not be necessary to purchase every weekly report, so we are talking about around 60-70 USD (55 $+ some reports). You will need just one trade earning this amount to break-even, the rest is pure profit. And purchasing reports on single markets allow me also to take a closer look to other markets as well.
Critic point of the Plus Membership is that the detailed reports included in that level are at least for me quite useless as I do not trade such markets (Global MSCI All country World $ index, Global MSCI Emerging Markets $ Index, Global MSCI $ index, Global S&P Global 100 Index, Global S&P Global 1200 Index).
So the Plus membership would make sense only by purchasing reports on top, or investing 15$ additionally to get a regular detailed report of one market.
The reversals are only available in the detailed reports, not in the summary one. And it is not recommended to trade only based on GMW comments only.
