Investox EoD Data Connection: How to Connect the TAI-PAN EoD Data Feed
For systematic traders and technical analysts using **Investox XL** or **Investox ST**, having a reliable, clean, and deep end-of-day database is paramount for testing strategies and generating signals.
Combining the advanced rule-based logic of Investox with the error-corrected, high-quality historical database of TAI-PAN creates a robust standalone workstation.
In this guide, we walk you through the entire process of setting up a new Investox project powered by TAI-PAN End-of-Day (EoD) data, alongside a crucial technical fix if your software integration fails to connect.
Video Tutorial: Connecting TAI-PAN EoD to Investox
Prerequisites
To follow this setup, you need either [00:00:14]:
- A full retail or rental license of the desktop **TAI-PAN software** (EoD version).
- Alternatively, a standalone installation of the localized **TAI-PAN DB Engine**.
This infrastructure acts as the server backend that supplies historical data locally into your Investox software.
Step-by-Step Connection Guide
**Step 1: Create a New Project**
Launch your Investox application. From the main panel, initiate a new charting or strategy project workspace [00:00:30].
**Step 2: Initialize the TAI-PAN COM Connection**
If you don't have a pre-configured data profile active, click on **New** (Neu) to add a source [00:01:00]. From the interface provider list, explicitly choose **"Taipan 32 Bit com"** and click OK [00:01:00].
**Step 3: Map Your Securities and Indices**
A catalog window will pop up. Here, navigate through the available TAI-PAN indices (e.g., select the **DAX** segment) [00:01:12]. You can choose to add individual assets or map entire indices to your Investox tracker sheet.
**Step 4: Complete the Mapping**
Click **Finish** (Fertigstellen) [00:01:44]. Investox will pull the mapped securities into its database environment. The historical curves will load immediately, making the financial data fully ready for mathematical processing, custom indicators, and automated backtesting routines [00:01:52].
🛠 Pro-Tip: Fixing the Investox COM Interface Error
If Investox cannot communicate with TAI-PAN, it is highly likely that the underlying Windows COM components are unregistered or corrupt [00:02:01]. Follow these steps using the TAI-PAN maintenance toolkit to fix the bridge in seconds:
- Close Investox. Open your **TAI-PAN EoD** software (or its DB Engine configuration utility) [00:02:14].
- Navigate to **Update & Maintenance** (Update und Wartung) > **Configuration** (Konfiguration) [00:02:14].
- Locate your installation directory (the execution path folder typically named `Prog`) and open it [00:02:41].
- Find the system utility named **reutil.exe** and launch it with a double-click [00:02:41].
- Within the toolkit, you will likely see a status showing that core components (such as *TPAccess* or *tpacc20*) are not registered properly [00:03:01].
- Click **"Unreg All"** (unreg alles) to purge all legacy component definitions from your Windows environment [00:03:29].
- Once cleared, click **"Reg All"** (reg alles) to force-refresh and re-register the 32-Bit COM wrappers directly inside your active TAI-PAN workspace directory [00:03:49].
Reopen Investox and run your data link. The connection will now execute flawlessly [00:04:00].
Frequently Asked Questions (FAQ)
Does this connection support real-time data streaming?
No, this specific integration is designed for the TAI-PAN End-of-Day (EoD) data engine, which feeds historical daily prices into Investox. For real-time execution environments, separate automated streaming data feeds must be configured.
Why does my Investox show a 32-Bit COM interface mismatch?
Investox relies on 32-bit architecture wrappers to handshake with localized data systems. If Windows updates or software re-installations disrupt this layer, running the localized `reutil.exe` setup inside the TAI-PAN program directory cleans and re-establishes the necessary COM registrations instantly.
Can I export custom asset filters from TAI-PAN into Investox?
Yes. Any custom index, watchlist, or filtered stock scanner list that you save inside your localized TAI-PAN workspace can be browsed and mapped dynamically into your Investox strategy configurations.
