Hello, Eros1973ms & Big Mike Much thanks for your code. Could you tell me more hint that how the text correctly positioned and moved anytime when resize the chart? Does it is related the below vars for coding this effect? time_1(0), price_1(0), hours(0), minut(0),

Hi Futat, basically the dynamic positioning is obtained evaluating the variable date+time for the horizontal positioning and price for the vertical. This evaluation can be done using the "aiLeftDispDateTime" and "aiHighestDispValue", that change every time you resize the window with the values of the high-left corner of the window.

Hello, Eros1973ms
Much thanks for your teaching.
I adjusted the code in simple for easily studying and I am newbie, so I am using the FreeQuotes in daily chart.
So, I still have no idea why & how to activate the variable date from the left once I resize the chart.
Does it is FreeQuotes data problem? Or I miss something to make the variable of date_1 can be changed once I resize the chart?

Could you kindly teach me?

Code as below:
vars:
date_1( 0 ), price_1( 0 ), time_2( 0 ), textStr( "" ), offset_points( 0.1 );

date_1 = JulianToDate( GetAppInfo( aiLeftDispDateTime ) );

time_2 = ( HoursFromDateTime( GetAppInfo( aiLeftDispDateTime ) ) * 100 ) + ( MinutesFromDateTime( GetAppInfo( aiLeftDispDateTime ) ) ) + SecondsFromDateTime( GetAppInfo( aiLeftDispDateTime ) );

price_1 = getappinfo( aiHighestDispValue ) - 0.5 * offset_points;

once cleardebug;
textStr = "Futat";
once value16 = text_new( date_1, time_2, price_1 - offset_points, textStr );
value17 = Text_SetStyle( value16, 0, 1 );
value18 = text_setlocation( value16, date_1, time_2, price_1 - offset_points );
