Thats an:

ENUM_TIMEFRAMES

Chart Timeframes

All predefined timeframes of charts have unique identifiers. The PERIOD_CURRENT identifier means the current period of a chart, at which a mql5-program is running.

  1. On MT4: Unless the current chart is that specific pair/TF referenced, you must handle 4066/4073 errors before accessing prices.
              Download history in MQL4 EA - Forex Calendar - MQL4 programming forum - Page 3 #26 № 4

    The function linked to, opens a hidden chart for the symbol/TF in question (if not already open,) thus updating history, and temporarily placing the symbol on Market Watch (if not already there,) so SymbolInfoDouble(symbol, SYMBOL_BID) or MarketInfo(symbol, MODE_BID) don't also return zero the first call.

  2. You can't skip parameters in your iCustom call. Your image shows the first parameter is "Candle Trend Time Frames" a string (value likely irrelevant.) The second (2) through eight (8) parameters are the enumeration.

  3. Why did you post your MT4 question in the Root / MT5 EA section instead of the MQL4 section, (bottom of the Root page?)

    Next time post in the correct place. The moderators will likely move this thread there soon.

Then you are probably NOT using iCustom() correctly.

You are using MT5.

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 (after the indicator has updated its buffers), you use the handle, shift and count to get the data.
