In situations, where we do not need to calculate any indicators based on higher interval data, but rather just read OHLC, V or OI arrays – TimeFrameGetPrice<\/a><\/strong> is the most convenient function to use.<\/p>

To plot daily High and Low levels we just need to read the respective arrays calling: TimeFrameGetPrice(“H”, inDaily ) – the first argument specifies the array we want to read, the second argument defines the interval we are reading data from. As with any other TimeFrame functions – we can only read data from higher intervals, so it is possible to read daily data when we work with 1-minute quotes, but not the other way round.<\/p>

Here is a sample formula which draws daily high and low in the intraday chart:<\/p>Plot<\/span>( <\/span>Close<\/span>, <\/span>"Close"<\/span>, <\/span>colorDefault<\/span>, <\/span>styleBar <\/span>); <\/span>Plot<\/span>( <\/span>TimeFrameGetPrice<\/span>(<\/span>"H"<\/span>, <\/span>inDaily <\/span>), <\/span>"day high"<\/span>, <\/span>colorGreen<\/span>, <\/span>styleStaircase <\/span>| <\/span>styleThick<\/span>); <\/span>Plot<\/span>( <\/span>TimeFrameGetPrice<\/span>(<\/span>"L"<\/span>, <\/span>inDaily <\/span>), <\/span>"day low"<\/span>, <\/span>colorRed<\/span>, <\/span>styleStaircase <\/span>| <\/span>styleThick<\/span>)<\/code>

TimeFrameGetPrice<\/strong>() functions allow also to easily shift the reading by N-bars of the higher interval if we specify that in 3rd argument of the function, so calling TimeFrameGetPrice<\/strong>( “H”, inDaily, -1 ) will return the high of previous day.<\/p>

The following code draws high \/ low of previous day on top of the intraday chart:<\/p>Plot<\/span>( <\/span>Close<\/span>, <\/span>"Close"<\/span>, <\/span>colorDefault<\/span>, <\/span>styleBar <\/span>); <\/span>hlstyle <\/span>= <\/span>styleStaircase <\/span>| <\/span>styleThick<\/span>; <\/span>Plot<\/span>( <\/span>TimeFrameGetPrice<\/span>( <\/span>"H"<\/span>, <\/span>inDaily<\/span>, -<\/span>1 <\/span>), <\/span>"Prev High"<\/span>, <\/span>colorGreen<\/span>, <\/span>hlstyle <\/span>); <\/span>Plot<\/span>( <\/span>TimeFrameGetPrice<\/span>( <\/span>"L"<\/span>, <\/span>inDaily<\/span>, -<\/span>1 <\/span>), <\/span>"Prev Low"<\/span>, <\/span>colorRed<\/span>, <\/span>hlstyle <\/span>)<\/code>
