Hi Daniel,
Hercules is designed to run on the H1 time frame. It is not so much a scalper as a breakout EA.
That's strange that you are having problems with the EA... try re-compiling it.
There are also EUR/AUD and Commodity Crosses (USD/CAD, AUD/USD, NZD/USD) versions of the EA available for free. If interested just drop me a line at
forexportfolio@hotmail.com
Happy Trading!
