# Data and trading from different data feeds

In Overcharts you can configure an instrument to receive data from a data-feed and execute orders on another.

**Follow these steps to set in the instrument configuration a real time & historical data feed different from the execution one:**

**1.** From **Overcharts main window** > **Instruments** Tab

- **Access configuration of the instrument connected to data-feed WHERE YOU WANT TO PLACE ORDERS. For example, if you want to place orders on Interactive Brokers, access configuration of the instrument connected to Interactive Brokers**
- If the instrument is not already included in the instrument list, add it from *Overcharts *main* window* > ***Instruments** Tab* > ***Add Instrument** button*

> Main connection is always the trading connection

**2.** Go to **Real-Time**Tab

**3.** Select the new connection for receiving real-time data

**4.** Data feeds often have different symbols to identify an instrument. Customize the instrument symbol by selecting the **Customize Symbol** check-box.

If you do not know the exact symbol (and/or exchange code) used by new data-feed to identify the instrument, ***please use the dictionary to look up the symbol (RECOMMENDED)***

**FUTURES ONLY**:

If **rollover** management is enabled in a **futures** instrument, the **Futures Symbol Format** must also be set. Be careful to select it correctly otherwise the symbol will be *wrong* and you will not receive any data.
Instrument symbol MUST always coincide with the symbol used by data-feed to identify the instrument. If you have any doubts about the symbol, refer to the official application of your data-feed and/or ask their support.

Be careful to select the correct*futures symbol format* depending on instrument and the number of digits used to represent the year (usually 1 or 2 digits). If in the *futures-symbol-format* list you do not find the correct *futures-symbol-format* (*very rare* case), then create a new one from **Overcharts main window** > **Instruments** Tab > **Futures Symbol Format**.

Furthermore, only symbol **root** must be defined in symbol field, that is the fixed part common to all contracts of the instrument (eg in ESM21 the root is ES).

**5.** Go to **Historical Data & Time Frames** Tab and check if the same data-feed + symbol has been automatically set as data-feed for historical data. If it is different, change it manually by following the instructions given in **step 4**

**6.** Save the configuration

**7.** Clear instrument database to delete existing data (optional but recommended):

- ***Instruments*** Tab > *Right Click* on instrument > ***Clear Instrument Database***
