Results on EUR/USD @ M15

Backtesting this expert advisor on the EUR/USD @ 15-minute timeframe shows that the Expert Advisor is very lossy. The EA is, in fact, limited by the use of only one indicator. This isn't enough to establish accurate entry points. The situation does not become profitable in other timeframes and it isn't suggested to use this EA on a real trading account.

Strength

The expert advisor works well only in case of a clear overbought or oversold situation that triggers a trend reversal.

Weakness

The stochastic oscillator alone is insufficient to determine correct entry and exit signals. It should be integrated with other indicators.

The example chart screenshot below shows a series of three losses in a row generated by this EA:

What Is It Good For?

Although it couldn't be recommended for the use in a live account, this expert advisor can be used as a foundation for further development and optimization. You need to understand that it is not profitable on its own because it is affected too strongly by false reversals.
