RSI is not updating

New comment
  
void OnNewCandle()
{
   rsi_value = iRSI(symbol, period, 14.0, PRICE_CLOSE);
}

So, i have made this code (this is a custom function that run at the oppening of a candle), but the RSI is stuck to 10.0 forever.
In the chart i see its updating correctly, but in the code its stuck at 10.0.

Any idea why ?

That is the handle to work with the indicator.  Now you must use copybuffer to get the data
  
void OnNewCandle()
{
   rsi_value = iRSI(symbol, period, 14.0, PRICE_CLOSE);
}

Perhaps you should read the manual, especially the examples.

They all (including iCustom) return a handle (an int). You get that in OnInit. In OnTick/OnCalculate (after the indicator has updated its buffers), you use the handle, shift and count to get the data.
