1) The Web manual page is outdated and does not show GET_TRADES and brokerTrades() like the Zorro helpfile does.
2) If Zorro calls GET_TRADES, how does Zorro know how to size the TRADE array buffer? Does Zorro necessarily invoke GET_NTRADES first? If so, there should be a check mark under the "Internal" column for GET_NTRADES and clarify that the plugin should also support GET_NTRADES alongside GET_TRADES.
3) GET_TRADES does not have a return value specification. Is it the number of trades?
