want to draw a trendline
There is no such thing as the "corner of the candle". Candles are just "visual artifacts" to represent the OHLC data and they have no set thickness. They can be "thick" or "thin" depending on the zoom level but have not set conditions for their precise display.
A start and end anchor points of trend-line graphical objects are based on price quotes and time, not on precise bitmap coordinates.
Endpoints of a trendline are on the candle center. The time of the candle.
You would have to compute the candle's width and distance between candles, in pixels. And then convert that to times for the endpoint(s).
Even when you get that right, the moment you change candle width, the line is wrong. Therefor you can't use it for trading. Why bother?

My trading time frame is one minute, and I want quick reaction in binary options.
How can I count pixels?
You can write the code and replace it.
Candlestick width is always the last zoom.
thanks
You seem to be ignoring our advice. As explained the candle thickness will vary with the zoom level irrespective of it being M1 or not. It will also change with Screen DPI.
You are analysing your situation incorrectly. Even if you did know the pixel count it would make no difference because the trend-line anchor points are not based on pixels, but instead on time and price.
Rethink your logic. It is flawed.

hello Mr Carreiro
This indicator is not drawn for the new candle. I must change the time frame for it to change. What should I add?
string objname1="LINEee" //+------------------------------------------------------------------+ //| Custom indicator initialization function | //+------------------------------------------------------------------+ int init() { //---- Output in Char //---- return(0); } int deinit() { ObjectDelete(0, objname1); return(0); } //+------------------------------------------------------------------+ //| Custom indicator iteration function | //+------------------------------------------------------------------+ int start() { /////////////////////M1 double high1= iHigh(Symbol(),0,2); double close1= iClose(Symbol(),0,1); datetime time2= iTime(Symbol(),0,2); datetime time1= iTime(Symbol(),0,1); ObjectCreate(0,objname1,OBJ_TREND,0,time2,high1,time1 ,close1); ObjectSetInteger(0,objname1,OBJPROP_COLOR,clrAqua); ObjectSetInteger(0,objname1,OBJPROP_STYLE,STYLE_DOT); ObjectSetInteger(0,objname1,OBJPROP_WIDTH,1); ObjectSetInteger(0,objname1,OBJPROP_BACK,false); ObjectSetInteger(0,objname1,OBJPROP_SELECTABLE,false); ObjectSetInteger(0,objname1,OBJPROP_SELECTED,false); ObjectSetInteger(0,objname1,OBJPROP_HIDDEN,false); return(0); } //

You should stop using the old event handlers (init, start, deinit) and IndicatorCounted() and start using new event handlers (OnInit, OnTick/OnCalculate, OnDeinit).

You created the object on one tick. You can never create it again; including a new candle.
Either delete and re-create it, or move it if it already exists.
