Enable mouse tracking, in OnChartEvent when mouse move, take the coordinates and convert to price/time. What's the problem?

hi everybody
I need to get the index of the bar when the mouse hovers over that bar.
I am using MT4
Does anyone have help?
Thanks.
Try this example :
#property strict /* first you need to store the previous coordinates of the mouse */ int previous_x=0,previous_y=0,previous_click=0; int OnInit() { //reset on init previous_x=0;previous_y=0;previous_click=0; //enable the mouse track ChartSetInteger(ChartID(),CHART_EVENT_MOUSE_MOVE,true); return(INIT_SUCCEEDED); } void OnChartEvent(const int id, const long &lparam, const double &dparam, const string &sparam) { //--- //when the mouse moves if(id==CHARTEVENT_MOUSE_MOVE){ //grab the x y and click int x=(int)lparam,y=(int)dparam,click=(int)StringToInteger(sparam); //if the x or the y are different you are interested if(x!=previous_x||y!=previous_y){ //you need to get the time where the x axis of the mouse is pointing at datetime time_result=0; double price_result=0.0; int subwindow_result=0; ChartXYToTimePrice(ChartID(),x,y,subwindow_result,time_result,price_result); //now you have the time at the location of the x // the price at the location of the y // and the subwindow # /* So , if the time returned is <= Time[0] */ if(time_result<=Time[0]){ //then look for the bar index int barTarget=iBarShift(_Symbol,_Period,time_result,true); Comment("Bar["+IntegerToString(barTarget)+"]"); }else{ Comment("No Bar"); } } //pass the x y and click to the previous for recalling later previous_x=x; previous_y=y; previous_click=click; } } void OnTick() { }
