March OptionWorkshop updates v21.3.2294 🌱
==========================================

Performance optimization, strategy charts improvements, and a lot of behind-the-scenes improvements.

:::cut:::

## Updates

* The **Instruments board** now supports custom sorting. You can drag & drop rows by holding the **Alt** key.
* User-defined strategy chart zooming will be saved when switching between strategies with a bound chart window. The **FitToView** button resets zooming.
* On startup, the OptionWorkshop loads all accounts/trades/positions from the local database. This process was quite slow for databases with a significant number of trades. We’ve optimized it, and now it is 4-5 times faster.
* Pressing the Bind button on the strategy chart window triggers binding instantly.
* The instrument tree is limited to the base asset node in the **position manager** when adding positions through the "+" button.
* Renamed columns in the **position manager**:
    * Position type → P.T.
    * Vola → IV
    * Commission → Comis

## Bug fixes addressed the following issues:

* The toolbar in the volatility chart window was blinking and changing its size.
* Dr.Web detected a virus in **OW.Math.exe** by mistake.
* Update errors when changing the update channel.
* Incorrect location of sliders in the **Price range** on the anchored strategy chart when switching between strategies.
* Incorrect calculation of the price for the total strategy in the **positions manager** table.
* Errors when loading market data from cache for expired instruments.
* Delta hedger didn’t save the center of the hedging range if it (center) was set manually by a user.
