Hi,

I would like to change the RSI period to 3 from the default value of 14.

For some reason when i try to change the period to the value of 3. When i try to back test my strategy it will default the value to 15.

Does anyone else also has this problem or just me?

Please feel free to give me some advice.

thanks you

My code are as below:


I guess you are running your backtest on M15 timeframe.

Where in this code is the period of RSI changed ?

  1. Where are you even trying to set it to 3?
    double iRSI(string symbol, int timeframe, int period, int applied_price, int shift)
    R1 = iRSI(NULL,0,                            Period(),       PRICE_CLOSE,0);
                                                   ^ Length of the RSI =  1 on M1  chart, 
                                                                       = 15 on M15 chart
  2. Check your return codes What are Function return values ? How do I use them ? - MQL4 forum
  3. Adjust for 4/5 digit brokers
