you need to change brokers... plain and simple. There's just no way you can run that type of EA with an account that doesn't allow micro lots. I've had the same experience in the past with FXOpen and it just killed my account.
It looks like FXShuffle has completely changed its behavior since mid March. It is now focused on capital preservation rather than profit accumulation. In other words, it's playing it safe. And I think I know the reason why.
When was FX Shuffle released to the public? You guessed it, not long after it started to dramatically reduce lot size. Because they don't want to gamble on the profitability proof they've already established. They worked hard to raise that account up to 120% + but now the real challenge is to keep it this way so that they can sell the maximum copies of the EA. Risking more money right now and possibly putting a dent on that good looking equity curve would be like trying to sell a brand new car with a broken headlight. Sure it's a quick fix, but it's no longer new. But it makes sense, because people want the steady growth, not the roller coaster ride.
Once the dust settles and the marketing campaigns are quiet, we might see a lot size increase. But let's hope the results keep the same trend.
