Generally it is the case when the out of sample results do not reside within the bandwidth of the optimized period.

When there are lots of optimizable parameters for the EA, it is prone to fitting the curve.

 
Something was described in this article: How to Test a Trading Robot Before Buying
And there is discussion thread about it: Over-optimization (curve fitting)

Buying a trading robot on MQL5 Market has a distinct benefit over all other similar options - an automated system offered can be thoroughly tested directly in the MetaTrader 5 terminal. Before buying, an Expert Advisor can and should be carefully run in all unfavorable modes in the built-in Strategy Tester to get a complete grasp of the system.
 
Thank you!
