MQL5 - HIstorical Camarilla- Need HELP for easy mod

hi !

I'm a fan of camarilla pivots . By serveral years I use amibroker to calculate plot and in every frames.

I have found in mql5 web site a free indicator "camarilla historical".

Here a link to full easy code. http://www.mql5.com/en/code/viewcode/1680/20984/cam_h2_h5_historical__3.mq5

It calculate the classic daily pivots based on previous daily High Low Close.

I want add a input parameter "timeframe" so I can calculate them from High Low Close of H1 H4 Week Monthly or others frame.

I'm new to mql5 but I tried :

added this

input ENUM_TIMEFRAMES      period=PERIOD_D1;

and changed this part of coe

  ArraySetAsSeries(Time,true);
  ArraySetAsSeries(Low,true);
  ArraySetAsSeries(High,true);
  ArraySetAsSeries(Close,true);

with this

  ArraySetAsSeries(Time,true);
  CopyTime(_Symbol,period,0,rates_total,Time);
  ArraySetAsSeries(Low,true);
  CopyLow(_Symbol,period,0,rates_total,Low);
  ArraySetAsSeries(High,true);
   CopyHigh(_Symbol,period,0,rates_total,High);
  ArraySetAsSeries(Close,true);
   CopyClose(_Symbol,period,0,rates_total,Close);

But i get errors whem compiled :(

Can somene help me with this mod ? Please please ..so i can remove amibroker

Big thanks in advance !

sorry im ******, i have read something more about mql5 and found that my mod can't work. So forgot it.

the only things that is right :

input ENUM_TIMEFRAMES      period=PERIOD_D1;

Can someone suggest how I can do ? Which changes to OnCalculate function to work on obtain HLC from period ?

thanks :)
