I have this simple afl for plotting Previous day High/Low and Close. But after sometime the chart becomes compressed. Need help in keeping the scale of the chart same

=================
xx = DateNum() !=Ref(DateNum(),-1);
bt=LastValue(BarsSince(xx))+1;

Hcolor=ParamColor("High Color",colorPink);
Lcolor=ParamColor("Low Color",colorSeaGreen);
Ccolor=ParamColor("Close Color",colorBlue);

mh=TimeFrameGetPrice( "H", inDaily, -1 );
ml=TimeFrameGetPrice( "L", inDaily, -1 );
mc=TimeFrameGetPrice( "C", inDaily, -1 );

//Plot(mh,"",colorPink,styleDashed|styleNoLabel);
//Plot(ml,"",colorSeaGreen,styleDashed|styleNoLabel);
//Plot(mc,"",colorLightBlue,styleDashed|styleNoLabel);

Plot(LineArray( BarCount-bt, LastValue(mh,1), BarCount-1, LastValue(mh,1), 0 ),"", Hcolor,styleDashed);
Plot(LineArray( BarCount-bt, LastValue(ml,1), BarCount-1, LastValue(ml,1), 0 ),"", Lcolor,styleDashed);
Plot(LineArray( BarCount-bt, LastValue(mc,1), BarCount-1, LastValue(mc,1), 0 ),"", Ccolor,styleDashed);

How can we access Time and Sales data in Amibroker's AFL to plot indicators.

Found the GetRTData following command in Amibroker.
"Bid = "+GetRTData("Bid");
"Ask = "+GetRTData("Ask");
"Last = "+GetRTData("Last");
"Vol = "+GetRTData("TradeVolume")

But how to use it to plot indicator in realtime so that it picks every trade (as in time and sales window) and plots Ask-Bid volume in realtime.

Amibrokers Time and Sales windows shows this Ask-Bid volume in the bottom statistics. Is there any way to plot it as an indicator (preferably in candlestick form so the its shows open, high, low and close values of Ask-Bid volume).
