GET_MAXTICKS is not for the end user, but instructs Zorro to download data in the returned packet size. The plugin developer, not the end user, is supposed to experiment with this value.

The price source switch command could also be used for switching to RT bars. It they are not a big hassle to implement, we can include them.

Zorro can send real stops to the broker, but the IB plugin does not support them. AFAIK the IB API has no stop order, but requires two orders instead.
