Block trade identification

[torch2k]

Hi, how can I tell if a block trade is posted as a buy or sell order?

Hello torch2k,

Thank you for your post.

To determine the position of orders made you could use the Account class and loop through your account positions to print the position Quantity, MarketPosition, and AveragePrice.

See the attached example script demonstrating how this could be accomplished.

Also, see the help guide documentation below for more information.

Sorry, i don't think I was clear enough in my initial question..

I am using an indicator that I found supplied on here called TnSVolumeExample. It draws orders on the chart based on a certain block size using "OnMarketData". I'd like to know if it is possible to determine if these large blocks are sell orders, or buy orders.

Hello torch2k,

Thank you for the clarification.

You could do something similar to the BuySellVolume indicator that comes default with NinjaTrader. The BuySellVolume indicator uses OnMarketData() to check if the price is greater than or equal to the Ask to determine the number of buys made and it also checks if the Price is less than or equal to the Bid to determine the number of sells made.

I see the TnSVolumeExample already checks if the Price is >= the Ask and checks if the Price is <= Bid within OnMarketData(). You could consider simply changing the text of the Draw.Text() methods so that they draw something like "Buys" or "Sells".

For example, see below:

Draw.Text(this, "My text 1" + marketDataUpdate.Price.ToString() + CurrentBar, true,[B] "Buys: " + priceLevelsAsk[marketDataUpdate.Price.ToString()].ToString()[/B], -1, marketDataUpdate.Price + offset, 0, Brushes.Green, new SimpleFont("Arial", 11), TextAlignment.Center, Brushes.Transparent, Brushes.Black, 100);

See the BuySellVolume indicator that comes with NinjaTrader for an example of determining buys and sells. To view the BuySellVolume indicator code, open a New > NinjaScript Editor window, open the Indicators folder, then locate and select the BuySellVolume indicator.

Also, see the help guide documentation below for more information about using OnMarketData().

Ok, thanks. Just to be clear though, this is not telling me if the order is a specifically a buy or a short though, right? Just if the sale price was above ask or below bid?

Hello torch2k,

Thank you for your note.

That is correct. Buys would be considered as the price above the Ask. Sells would be considered as the price below the Bid.
