Preamble
Depth of Market also known as Level II or Order Book is a specific market data that provides information on the number of limit orders (available static liquidity) at different price levels.
Bid price is the price at which buyers are willing to purchase the product (futures contracts or securities).
Ask (Offer) price is the price at which sellers are willing to sell the product.
Best-Bid-Offer (BBO) or Level I represents the lowest ask and highest bid available at the time.
DOM Bricks Catcher is a simple, fast and handy tool that continuously scans the DOM for big limit orders and places detected orders on the price chart.
The indicator functions only on real-time data (live data) and does not plot any values on historical data as the required Level II data is only available in real-time.
An actual depth of Level II price levels seen by NinjaTrader and the indicator may vary widely depending on the data vendor and traded instrument (futures contract). For example, it may be provided more than 100 levels of depth for E-Mini S&P futures, while for some other futures it may only be available just 10 levels of depth, so the scan region amounts to the ten bid price levels and ten ask price levels nearest to the current price.
Features
-

-
Customizable audio alerts. You can use separate wav audio files as alerts for different conditions.
Sample wav files can be found here.
-
Marks of all catched 'big lots' won't disappear off the chart after changing the periodicity of the chart (timeframe) or after using 'Reload NinjaScript (F5)'.
Main Parameters
-
1. Trigger Size. The price levels in the DOM that have the quantity of limit orders exceeding the specified value of "Trigger Size" parameter will be marked on the price chart.
Do not use too small Trigger Size. This may lead to excessively frequent triggering and, as a result, performance degradation and unneccessary memory consumption.
-
2. Min Position in DOM. Works as an additional preliminary filter by position in DOM. Example: "0" means all DOM levels including Best-Bid-Offer will be taken into account. "9" means that only outermost bid and ask DOM price levels will be consided.
-
3. Position Tracking Mode. This parameter affects the filtering by Position in DOM. It has two options.
-
Update the Position of the Brick as it comes nearer to the Best Bid-Offer levels. — This is default mode. It may be useful if you use the "on-the-fly" filtering by the Position in DOM to try to dissect "real" big limit orders ("Bricks") from fake/flashing big lots. Fake orders are not intended to be filled, their actual purpose is to provoke the crowd to rash acts. So they are often moved away off the current price to steer clear of the Best-Bid-Offer.
Flashing orders also are aimed to test a reaction of competitive bots to reveal their presence and to examine a short-term price elasticity. Use the Position of the Brick in DOM where it was initially detected.
-
Audio Alerts
It is possible to use separate wav audio files as alerts for different conditions: on which side a big order appeared, bid or offer, and how close to the current price it was detected.
Sample wav files can be found here.
You can specify absolute path to your wav file using Open File dialog window.
Notice also, a wav file specified by filename only (without full path) will be sought in the following folders:
• 1. Your "Documents\NinjaTrader 7\bin\Custom\"
• 2. "c:\Program Files (x86)\NinjaTrader 7\sounds\"
Handy Drop-Down Button
First of all, by using the toolbar button you can hide temporarily all the markers drawn on the chart. Click on the "Bricks" toolbar button to toggle the visibility of on-chart markers.
Click on the drop down arrow of the "Bricks" button to get a drop-down menu that provides quick access to additional “on-the-fly” filter and other functionality.
Force Chart Refresh — If checked then the chart will be refreshed each time as new Big Size (aka Brick) is found out in the DOM.
The forcing may be recommended to use if you trade a non-liquid instrument where trades occurs not so often and even price (best bid-offer level) can move without any trading activity.
Clear All Bricks — Purges all “Brick” markers gathered during trading time.
