price crossing the ray, and use the slope to filter a signals

[aekzof]

Hi
please I need your help when
When have a signal, a buy or sell an order is executed
I'm still waiting for another a candle from the signal to draw a ray
so I have:

BarAgo=Currentbar-1 -------------------->signal
Currentbar


with these two informations I can calculate the slope

x1 = ChartControl.GetXByTime(myRay.StartAnchor.Time);
x2 = ChartControl.GetXByTime(myRay.EndAnchor.Time);
y1 = myRay.StartAnchor.Price;
y2 = myRay.EndAnchor.Price;

slope = (y1 - y2) / (x1 - x2);

now the market is moving

I have some questions

• By using this ray (slope) I would like to add a condition so that no order is executed until there is a crossover.

after my remarks there will be signals and false signals so I must avoid them

• how to calculate the crossover point ( price crossing the ray)

I am working on that one. But I don't know the result yet.

X3 = ChartControl.GetXByBarIndex(ChartBars, Bars.Count - 1);
y3 = y1 - slope * (x1 - x3);


Thank you for your patience and the time you devote to us

Hi aekzof, thanks for posting. The value of the "Slope" variable is likely nowhere near the price value on the chart, so I assume you would want to detect the cross of the price and the ray value. The CrossAbove/Below methods can take a Series and a static double value to calculate the cross between a price value and a static value, like a singular point on a ray.

Our colleague made this script that gets an X/Y value based on a rays slope:
