Here is the solution I use …

```
HideTestIndicators(true);
double MA1c = iMA(Symbol(),TimeFrame,ma1Period,0,MODE_EMA,PRICE_CLOSE,0);
double MA2c = iMA(Symbol(),TimeFrame,ma2Period,0,MODE_EMA,PRICE_CLOSE,0);
double MA1p = iMA(Symbol(),TimeFrame,ma1Period,0,MODE_EMA,PRICE_CLOSE,1);
double MA2p = iMA(Symbol(),TimeFrame,ma2Period,0,MODE_EMA,PRICE_CLOSE,1);
double RSI = iRSI(Symbol(),TimeFrame,rsiPeriod,PRICE_CLOSE,0);
HideTestIndicators(false);
```

If you do the same as above, indicators will not show after the the back-test finish or stopped.

As a result, no one can know what indicators you are using. I suppose this is what you are looking for.
