Wall Street Forex Robot supports the AUDUSD currency pair as default, there is no need to set the EURUSD pair. I think, the TP of 70 pips is somewhat big. It brought better results with a 15-pips TP when running the last few months on the strategy tester, but for the time being I will keep the default setting. I set Secure Profit and the trigger value of Secure Profit to 10/40. With this new setup, I let the ea trade the AUDUSD pair on my live accounts again.
I started to run a WS on my Think Forex demo account, because I think, there is some room for it beside the Million Dollar Pips. For now, the results are gathering on the demo account, and I will select the pairs that I will run on my live account on the basis of these tests.
I would like to note that in case you cannot devote 1-2 months to test a forex robot, it is better not to deal with it at all, because less time is usually not enough to find out what it is able to do.
