We "discovered" a bug (because mdub kindly told us about it) that Wealth-Lab's WealthSignals Trader tool was downloading the wrong sizing for a subscription. In fact, the subscriber's sizing factor was not applied.
This error was fixed today. In case you've used the WS Trader to enter trades, check the sizing for your exit signals. Or, you can rest easy by checking the Preferences > Trading > Exit Orders option in Wealth-Lab to always exit the full Position currently held.
