You may encounter a situation where your pending orders are not executed.

Canceled pending orders

A delayed order can be canceled for 2 reasons:
When a customer intentionally cancels their pending order.
When a pending order is canceled due to expiration.

Pending orders have been removed

A pending order may be deleted due to low leverage or insufficient funds.
A pending order is automatically deleted if there are insufficient funds to open it.

 Cancellation/Gap or stop loss violated (SL violated)

When the client receives a [cancelled/gap] or [SL violated] error message, the pending order is not executed due to the slippage rule. Stop orders and limit orders may not be executed due to the slippage rule. The stop order may not be executed if the take profit price is lower than the activation price.
 
Another reasons:

When demand significantly exceeds supply, or vice versa, there may be a delay in execution.

One way to detect low liquidity is to look at the candlestick price chart. Market conditions with low liquidity favor infrequent price updates, resulting in very high or completely flat candles.
