I have been using Robominer for nearly a year now, in both test and live environments. I currently have 2 live accounts running it, and in fact, after testing many EA's, RM is the only one I use now.
The results shown in FPA are misleading, because they offset actual profit with the paper "loss" of open trades. RM's methodology requires a lot of open trades that will be in the red for some time -- it is a grid-trading method.
This disguises the fact that every closed position is a winning trade!
I've traded Robominer for over a year and it has been consistently profitable on the AUDNZD pair. Not so its other pair, the EURCHF. You must go into RM with your eyes open and be aware that safety with RM is premised on trading only recommended lot sizing and the market staying within historical limits. When the market is well within those limits all is rosy and there can be a temptation to overtrade lot sizes. This will bite you very hard when the limits are approached or broken...as has now happened. The EURCHF lower limits have been blasted to hell and traders using that pair would be either out now or in very deep open draw down. Fortunately I only trade the AUDNZD pair. The standard FPA format for assessing an EAs performance does not fit Robominer's trading strategy because open draw down is shown as a loss. If you just trade AUDNZD, stick to the recommended lot sizing and do not mind seeing a temporary but sometimes unsettlingly large DD, then the Robominer is a profitable set and forget investment type of EA, delivering around 50% pa on initial balance. Actually however I much prefer the vendor's later product "Pipstrider" which also provides a similarly steady return but with more controllable draw down risks.
I have found that Robominer worked fine for me trading the AUDNZD pair as long as I stay within the guidelines.
Bob llewellyn, the creator of the Golden Grid and developer of Robominer recently released PIPen which is his second generation version. It is more self contained, more 'investor' friendly and is provided with a fully automated computer server and 24/7 monitoring service that includes installation etc.
He's posted on his technical research forum forex-assistant.com in recent months updates on Robominer settings and commentary on the currency pair that is pretty useful.
On that forum for existing licenced users of Robominer is a limited-time offer of switching to PIPen.
I am sure some kind of logic has been applied in this EA!!
I only checked EURNZD yesterday. It looks like it opened trade after the gap was closed. Eurnzd closed at 1.7952 on friday and opened at 1.7932 on sunday eve. Then it closed the gap straight away then came down and then went back up. EA placed buy at 1.7969!!!!!!!!!!
Price went up after this but did not reach target profit.
Is it really a sunday gap magic or one of those EA which place many trades and hold them for a long time?
