## What is Trading Simulator? <a href="#what-is-trading-simulator" id="what-is-trading-simulator"></a>

Trading Simulator is a specially designed trading tool that allows emulating the execution of orders for any connection, including those that do not allow trading.

For whom it will be useful? For any trader - from beginner to pros, trading in with any type of instrument. For example, crypto traders who do not have real accounts on a crypto exchange can trade in the demo mode on the selected crypto exchange.

## General settings <a href="#general-settings" id="general-settings"></a>

In the general settings, you can set the initial balance for the test account, set the delay in execution, and configure the settings of netting for each instrument.

**Initial balance** — the amount of money for the test account.

Trading Simulator creates separate trading accounts for each base currency of the instrument. For example, if you chose EUR / USD currency pair, then the account name will be **Account (USD)**, if you select EUR / JPY, then the name will be **Account (JPY)** respectively.

* **Execution Delay** — the length of time between the acceptance of an order and its execution. In the real market, this parameter affects on the slippage. There are 3 options for the delay: *Range*, *Fix* and *None* (instant execution).
