That sounds great, but you could question whether the near term robot doesn’t lose more than the long run expert advisor can recoup. The solution is found in the right cash management rules. If you manage the money and risk correctly, you can make fast money and have your losses covered by the long term methodology. Of course it is not failure-proof and you are likely to lose more in short term, however the concept is good. The crucial thing to keep in mind when mixing these two methods is that you should run the long run strategy first and trade with the short term robot in the frame set by the former.
