Thanks.
If I had that setting, I'd be using it for sure! Unfortunately, I don't have any settings for GT-Shadow which would do that. You could probably come up with your own, but the whole
point 
of GT-Shadow is for users to experiment and see what they can come up with. It's not an "out-of-the-box" robot that just runs like most others, it's designed for folks who want to try different strategies and come up with their own ideas.
That's not to say it's not possible, of course. If you didn't mind a lot of risk, and thought - or more aptly, you were SURE - the
currency 
was going to fall from the historical high (AUD/NZD) that it is at right now, then all you would have to do is make the lot size larger. However, if you were wrong and the pair goes the other way, then you would carry too much draw down and be closed out.
RM and GTS are designed to trade safely within the grid *IF* you have enough equity. With $5k and trying to make $2500 each month, you would be hard pressed to be successful. However, you could probably make $500 to $1000 much more easily. Then after several months, you could change your settings to be higher. Of course, you have to keep an eye on the grid to see what is going on, lest you carry too many open trades while you wait for things to come back around.
So, with all Forex trading, it's risk - how much can you handle?
