If, during your operations, you noticed that it’s not possible to edit the quantity of simulated orders and that they are not executed at the current asset quotation, please be aware that this is the expected behavior of the BlackArrow simulator.
In the BlackArrow simulator, it is not possible to edit the order quantity, following market standards. For a trade to be executed, there must be corresponding offers on the market's counterparty that can fulfill the orders sent by traders. The execution of these orders takes place at the Bid (best buy offer) and Ask (best sell offer) lines of the Order Book.
The BlackArrow simulator, order execution is based on the price at the top of the book. This means the price at which an order will be filled depends on the best available offer in the order book at the time of execution.
To add the Bid and Ask prices to the chart, right-click on one of the candles:
Note below that a buy order was placed above the current quotation price and no execution occurred, but after moving the order to the Ask Price, the order is filled.
The same happens for Market Orders. Note that when we click on Buy At Market the order is filled in the Ask Price:
In other words, the buy order will be executed when the green line, corresponding to the Ask, is reached. Conversely, for sell orders, the execution will occur when the yellow line, corresponding to the Bid, is reached.
This approach is used to make the simulation more realistic, mimicking the functioning of the real market on which the simulator is based. In the real environment, trading prices are determined by the buy and sell orders in the order book, and the execution of orders depends on the availability of counterparties willing to accept these offers.
However, it’s important for traders to be aware that this execution logic may result in trades being executed at prices different from those shown in the asset’s quote when the order is placed. This happens because the price at the top of the order book can change quickly as new offers are added or removed from the market.
Therefore, traders using the BlackArrow simulator should understand the order execution dynamics and be prepared to adapt their strategies according to the simulated market conditions. It is essential to practice an informed trading approach, analyze the order book, and monitor the best buy and sell offers to make informed decisions during the simulation. The experience gained in the simulator can be valuable when facing the real challenges of the financial market.
