transferring slope or angle to different time frames

[ballboy11]

I have been working a few days trying to figure how to get the angle on different time frames and everytime I draw the anchor line it is the wrong angle

i extracted the informatio from a Ray line I have drawn.

I am trying to get an angle on a daily chart then transfer the angle to a minute chart

dTicks = dRayStartPrice - dRayEndPrice; //y coordinates RISE
dTicks = dTicks / TickSize; // Divide by ticks for chart

nResTime = nRayStartBar - nRayEndBar; // x coordinate number of bars

dResAngle = dTicks / Convert.ToDouble(nResTime);

dResAngle = dResAngle/tChartTimeFrameInMinutes;


The chart time frame in minutes will find out the number of minutes if daily tcharttimeframe in minutes will be 1440


when my function loads the resangle it is supposed to draw

double dAnchor1 = 0;
double dAnchor2 = 0;
double dAnchor3 = 0;

// check chart time frame if daily or weekly
if (Regex.IsMatch(BarsPeriod.ToString(), "Daily") == true)
tChartTimeFrameInMinutes = 1440;

if (Regex.IsMatch(BarsPeriod.ToString(), "Weekly") == true)
tChartTimeFrameInMinutes = 10080;



DateTime tTempTime1 = tTime1;
DateTime tTempTime2 = tTempTime1.AddMinutes(tChartTimeFrameInMinutes);

dAnchor1 = Bars.GetOpen(Bars.GetBar(tTempTime1));

dAnchor2 = (dResAngle * TickSize) *tChartTimeFrameInMinutes+ dAnchor1;
dAnchor3 = -1 * (dResAngle * TickSize)*tChartTimeFrameInMinutes+ dAnchor1;

DrawRay("InverseAngle", false, tTempTime1, dAnchor1, tTempTime2, dAnchor2, Color.Red, DashStyle.Dash, 2);
DrawRay("AnchorLine", false, tTempTime1, dAnchor1, tTempTime2, dAnchor3, Color.Green, DashStyle.Dash, 2);
this.tagList.Add(new TachEonForceDrawList("InverseAngle"));
this.tagList.Add(new TachEonForceDrawList("AnchorLine"));



it works well if it stays on daily chart but when to a 1 minute it is totally off and not the correct angle

Hello ballboy11,

This thread will remain open for any community members that would like to assist with your custom math and logic.

That said, there is a formula that I have saved in my notes that may be beneficial to you, however, this formula is not supported by NinjaTrader Support.

Converting slope to angle:

Math.Atan2((startY - endY), numberOfBars) * (180 / Math.PI));

That said, when debugging your code, are you finding that the prints of the start and end bars and prices are expected values when changing to the smaller time frame?
