Limit Orders
Limited orders are market offers. That is, the buying and selling intentions of the participants (players).
Buy limit orders are always placed at a price below the current market quote.
Sell limit orders are always placed at a price above the current market quote.
Market Orders
Market orders are executed immediately after being sent, at the best offer from the counterparty (i.e., at the ask and bid prices).
Stop Limit
Buy stop Limit are orders placed at a price above the current market quote.
Sell stop Limit are orders placed at a price below the current market quote.
Stop Limit order have a trigger price, which is the price set by the user, and the Stop Offset, which is a safety margin (it can be the same value), indicating how far the order can be executed, thus preventing order slippage. It requires a guarantee and, therefore, consumes balance. Most brokers do not allow Stop Limit orders.
Stop Market
Stop Market orders are different from market orders, as they are placed at a price that is not the best offer. When the price is reached, the order is immediately executed, hitting the market.
Buy Stop Market are orders placed at a price above the current market quote.
Sell Stop Market are orders placed at a price below the current market quote.
How to configure the Stop Order type
Go to Trade > Settings.
In the Stop Order field is is possible to select between Market or Limit Stop orders.
Note: Currently only the simulated account supports Stop Limit orders.
Order Execution
In BlackArrow, orders are executed based on the BID and ASK available in the order book. This means that, for an order to be executed, there must be a matching counterparty offer at the same price or better.
For example, in the case of a buy order, execution will only occur when there is a seller willing to trade at the specified price or at a more favorable one. If the top of the order book (ASK) does not reach the order price, the execution will not take place, even if trades occur at other price levels.
This behavior reinforces that execution depends directly on the availability of liquidity in the order book, and not solely on the occurrence of trades in the market.
