Key Features
The Trade Detector indicator offers several customizable features to suit your trading needs:

Transaction Volume Threshold: Specify the minimum volume for a transaction to be considered significant.
Time Interval: Set the maximum allowable time gap between consecutive transactions to detect rapid, large trades.
Visual Alerts: Customize dot colors and line colors for buy and sell transactions.
Sound Alerts: Configure different sound alerts for buy and sell transactions.
Text Display: Choose to display the transaction time or volume directly on your chart.
How It Works
The Trade Detector indicator analyzes transaction data in real-time to identify large trades that meet your specified criteria. Here’s a detailed breakdown of how it operates:

Transaction Volume: The indicator checks if the volume of the current transaction meets or exceeds the specified threshold.
Time Interval: It compares the time gap between the current transaction and the previous one. If the time gap is less than or equal to the specified interval, the trade is considered significant.
Buy/Sell Detection: Based on the closing and opening prices, the indicator determines if the transaction is a buy (closing price >= opening price) or a sell (closing price <= opening price).
Visual and Sound Alerts: For detected trades, the indicator draws a dot and a line on the chart, and plays a sound alert if enabled. The color and sound of the alerts can be customized for buy and sell transactions.
Text Display: Optionally, it can display the transaction time or volume next to the trade on the chart.
Configure Parameters:

Volume: Set the minimum volume for detecting large trades. (min 300)
Time: Specify the maximum allowable time gap (in seconds) between transactions.(1sec)
Text Size: Adjust the size of the text displayed on the chart.
Show Time/Volume: Choose whether to display the transaction time or volume on the chart or both
Use Buy/Sell Alerts: Enable or disable sound alerts for buy and sell transactions.
Buy/Sell Alert Sound: Select the sound file for buy and sell alerts.
Buy/Sell Dot Color: Customize the colors for buy and sell transaction dots.
Example Configuration
Here’s an example configuration for the TradeDetector indicator:

Volume: 500
Time: 1 second
Text Size: 13
Show Time: False
Show Volume: True
Use Buy Alerts: True
Buy Alert Sound: C:\Program Files\NinjaTrader 8\sounds\Bullish.wav
Use Sell Alerts: True
Sell Alert Sound: C:\Program Files\NinjaTrader 8\sounds\Bearish.wav

With this setup, the indicator will detect large trades with a volume of at least 500 that occur within 1 second. It will display the time of the trade, and use different colors and sounds for buy and sell alerts.

Practical Examples and Interpretations
To better understand how to use the TradeDetector indicator, let’s consider a few practical examples:

Example 1: Large Buy Order in an Uptrend
Imagine you are monitoring a chart in an uptrend. Suddenly, the TradeDetector indicator detects a large buy order (e.g., volume of 800 or more ) 

Interpretation: This large buy order could signify strong buying interest, confirming the continuation of the uptrend. Traders might use this signal to enter a long position, expecting further price increases. But also exhaustion and  a possible reversal
Example 2: Large Sell Order at the Bottom of a Downtrend
Now, consider a chart in a downtrend. The TradeDetector detects a large sell order (e.g., volume of 1000) at the low point of the trend, marking it with an orchid dot and line.

Interpretation: A large sell order at the bottom of a downtrend could indicate capitulation, where sellers are exhausting their positions. This might be a sign of a potential reversal. Traders might use this information to prepare for a buying opportunity, anticipating a price bounce.
Example 3: Multiple Large Transactions in a Consolidation Zone
Suppose the market is in a consolidation phase, with prices moving sideways. The TradeDetector identifies multiple large transactions within this zone.

Interpretation: Multiple large transactions in a consolidation zone can indicate accumulation or distribution. If the large transactions are predominantly buy orders, it might suggest accumulation, leading to a potential breakout upwards. Conversely, if they are mostly sell orders, it could indicate distribution, potentially leading to a breakout downwards.
