alert log with buy sell volume

[r68cervera]

Hello, good morning, I am developing an indicator that sends me an alert to the Alert file. For this I use the Buy Sell Volume indicator. And the condition has to be when the sales in a bar are less than 200.


//This namespace holds Indicators in this folder and is required. Do not change it.

namespace NinjaTrader.NinjaScript.Indicators
{
public class ComprasGraf1000 : Indicator
{
private BuySellVolume buySellVolume;

protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"Alerta cuando el volumen de ventas en una barra es menor que 200 contratos.";
Name = "ComprasGraf1000";
Calculate = Calculate.OnEachTick;
IsOverlay = false;
//AddPlot(Brushes.Orange, "VentaPlot");
}
else if (State == State.DataLoaded)
{
buySellVolume = BuySellVolume();
}
}

protected override void OnBarUpdate() zz0.hsllsi65gcmzz
{
if (CurrentBars[0] < 1)
return;

// Acceso al volumen de ventas actualizado de BuySellVolume
double volumenDeVentas = buySellVolume.Sells[0];

if (volumenDeVentas < 200)
{
Alert("CompraAlta", Priority.High, "Compras Grafico 1000: " + volumenDeVentas.ToString("N0") + " contratos", "Alert1.wav", 10, Brushes.Green, Brushes.White);
}
}

With this code what it does is write the updated sales number every few seconds (after having configured the indicator in the graph and having selected CONFIGURATE ON EACH TICK)

If I insert the indicator and in the CONFIGURATE option I select ON BAR CLOSE, it sends a message to the alert file every time a new bar is started PURCHASES GRAPH 1000:0 CONTRACTS

and what I want it to do is ONLY send me an ALERT when at the end of a bar the number of sales is less than 200
Thank you very much for the help

Hello r68cervera,

The closest solution for what you are asking would be to use OnBarClose, the first tick of the new bar is what closes the bar so that would be one way to know the bar was closed so you can get a value.

Thank you Jesse for answering so quickly, but I told you about it in the previous post.
If I put onbarclose, it sends me a message to the log of the bar that starts, saying that the number is 0

Hello r68cervera,

That would be due to how the buy sell volume indicator collects data, on the new bar it clears the collections that you are using to accumulate for the new bar so when you check the 0 bars ago value it would be 0. You would need to use the 1 bars ago value to get a value. This indicator can also only be used in realtime to pull data from its plots, that would look like the following which will show values after realtime bars elapse.

protected override void OnBarUpdate()
{
    if(CurrentBar< 1) return;
   BuySellVolume().Update();
   Print(BuySellVolume().Buys[1] + " " + BuySellVolume().Sells[1]);
}

Hi Jesse, thanks for your answer, but I've already tried that and it doesn't work for me either.

// Acceso al volumen de ventas actualizado de BuySellVolume
double volumenDeVentas = buySellVolume.Sells[1];

BuySellVolume().Update();
if (volumenDeVentas < 400)
{
Alert("CompraAlta", Priority.High, "Compras Grafico 1000: " + volumenDeVentas.ToString("N0") + " contratos", "Alert1.wav", 10, Brushes.Green, Brushes.White);
}

and the result it gives me is the same



and what I am looking for is that when the candle closes, if the number of sales is less than 400, send a message to the log file


In this example, you would have to send two alerts to the log file. the first at 22:01:28 because the number of sales is 338 and the second at 22:08:11 because there are 386






Thank you very much for your help

Hello r68cervera,

You need to structure the logic exactly like I had shown to get a value in realtime, you are calling Update after trying to get the value, that needs to be first.
