Duplicate: How Array is filled under different time frame?

Explorer is set to a periodicity of 5 Minutes.

Below is the code for testing

TimeFrameSet(in5Minute);

MA_5MINS = MA(CLOSE, 5);
WMA_5MINS = WMA(CLOSE, 6);

TimeFrameRestore( );

// 10 Minute Time Frame
TimeFrameSet(2 * in5Minute);

MA_10MINS = MA(CLOSE, 5);
WMA_10MINS = MA(CLOSE, 5);

TimeFrameRestore( );

Filter = 1;
AddColumn(BarIndex(), "Bar Index");
AddColumn(MA_5MINS, "MA_5MINS");
AddColumn(WMA_5MINS, "WMA_5MINS");

AddColumn(MA_10MINS, "MA_10MINS");
AddColumn(WMA_10MINS, "WMA_10MINS");

The 5 minute time frame appears fine. But the 10 minute time frame data starts filling way down.

I was expecting the 10 minute time frame data to be coming in from 9:50 AM.
(Switching periodicity to 10 Mins in Explorer to show what I was expecting).
