TimeFrameRestore
- restores price arrays to original time frame

Time Frame functions
(AFL 2.5)


SYNTAX TimeFrameRestore( tradeprices = False )
RETURNS NOTHING
FUNCTION The TimeFrameRestore function restores price arrays replaced by TimeFrameSet.

Note that only OHLC, V, OI and Avg built-in variables are restored to original time frame when you call TimeFrameRestore().

All other variables created when being in different time frame remain compressed.

To de-compress them to original interval you have to use TimeFrameExpand.

Tradeprice argument should be set to false.

EXAMPLE TimeFrameSet( in5Minute ); // switch to 5 minute frame

/* MA now operates on 5 minute data, ma5_13 holds time-compressed 13 bar MA of 5min bars */

ma5_13 =
MA( C, 13 );

TimeFrameRestore(); // restore time frame to original

TimeFrameSet( inHourly ); // switch now to hourly

mah_9 =
EMA( C, 9 ); // 9 bar moving average from hourly data

TimeFrameRestore(); // restore time frame to original

Plot( Close, "Price", colorWhite, styleCandle );

// plot expanded average

Plot( TimeFrameExpand( ma5_13, in5Minute), "13 bar moving average from 5 min bars", colorRed );
Plot( TimeFrameExpand( mah_9, inHourly), "9 bar moving average from hourly bars", colorRed );

TimeFrameRestore and RestorePriceArrays
is essentially the same function. So please note that calling TimeFrameRestore also resets the ticker set by eventual previous call to SetForeign()

The TimeFrameRestore function is used in the following formulas in AFL on-line library:
