Plot Dynamic Stop Loss

[liquid150]

This seems like it should be easy, but I am stuck. My strategy has stop loss orders change dynamically based on price distance and time from order entry. When I use AddPlot such that

            if (State == State.SetDefaults)
            {......
                AddPlot(new Stroke(Brushes.Red,2), PlotStyle.Hash, "Stop loss trigger");

and

        protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice, int quantity, int filled, double averageFillPrice, OrderState orderState, DateTime time, ErrorCode error, string comment)
        {
            if (order.OrderState == OrderState.Working && order.Name == "Stop loss"
                )
            {
                Value[0] = order.StopPrice;
            }
        }

I get plots for the stop loss level each time the stop loss is updated. But I can't seem to figure out how to get the plots to extend to bars where the position is still open, but the stop loss was not updated. Everything I try leads to stop loss level being plotted on all bars, and where there is no position it is zero. This is even the case if I try to limit the series being printed by means of:

protected override void OnBarUpdate()
........
           if (Position.MarketPosition == MarketPosition.Long || Position.MarketPosition == MarketPosition.Short)
            {
            Value[0] = Value[0];
            }

I feel like there is something obvious I am missing so I am asking here, is there a shortcut to accomplishing this? I can't null the Value[0] double...so I am stuck.

Hello liquid150,

Thanks for your post.

I recommend creating a double variable at the class level and assigning it the order.StopPrice in OnOrderUpdate().

Then in OnBarUpdate(), you can assign the double variable to the plot.

Thank you, sir. That did the trick. I had considered doing this but hadn't tried it, thinking it wouldn't solve the "printing on inactive position bars" problem. But it did.

Hello liquid150,

Thanks for your reply.

The main thing to keep in mind is that the plot is sync'd to the OnBarUpdate of the charts data series. The OnOrderUpdate() happens asynchronously to OnBarUpdate().

Indeed. I didn't realize just how early it occurred until adding this plot, which will help me fix an extremely rare situation where I get stopped out immediately on an order entry caused by this asynchronicity. So two birds with one stone I guess?
