Sometimes only a couple of seconds, sometimes 4-20 seconds
Yes, I'm full time in development to make many features works and low delay is coming too.
I'm really want to tell that first beta will be released within one month. But It still hard to calculate ETA.
It sounds very very good... I will beta test it

For me, your application is the best for non MT4 users.
If you can add these features in the future, it will be the Bitcoin trader that everyone will use

:
- Decrease trading/API lag.
- Add a way (like an server) for saving rules and apply them without a connection from QT Trader.
- Add graphs and the possibility to add stop loss and take profit to them.
- Fix the bug in graphic layout on OS X I reported.
Thanks again for your great job.
