Yes, it is a common knowledge for traders that slippage could happen for any type of orders in any financial markets.
The FXnet Trader by iForex is also the same, and slippage could happen when you place positions at anytime.
What happens with slippage
It is almost not possible that when slippage happen, it will find the next available price in favor of your position, but it will always find the price otherwise.
If your order couldn’t find the exact price you have quoted for, the trading server will automatically find the next available price and will execute the order with that price.
There is no maximum limitation on slippage, and it could happen anytime if there is no available position for your order.
Slippage on Stop loss order
Slippage even could happen on Stop loss orders.
When a stop loss order triggers, and it couldn’t find the enough liquidity in the market, it will find the next available price as it is the usual procedure of slippage.
As the money liquidity is always related to all financial markets, slippage could happen to all financial markets.
No slippage on account balance
With iForex, stop out triggers when there is no positive free balance in your account.
The stop out will liquidate your positions and your account balance could cause negative balance as a result.
But you do not need to worry about covering the negative balance, as iForex has set NBP(Negative Balance Protection) for all accounts.
If negative balance is found in any accounts, iForex will immediately fix the balance to zero.
As already mentioned above, market liquidity is one important element for all financial markets.
And Forex markets is the largest financial market in the world, so the market liquidity is deep and there are thousand of brokers in the world.
But the market liquidity at each moment is not so deep and you need to be careful of this.
For example, normally a broker secures a liquidity for one instruments about 2,000,000 – 3,000,000 units(dollars).
This equals to about 20 – 30 lots per symbol.
So, you may get slippage if you place an order more then 20 lots in most of the cases in any brokers.
The tightest spread they display in its trading platform may provide really low liquidity.
How to avoid the slippage
You can never complete avoid the slippage as it is a normal thing that could occur to any financial markets at anytime.
But you can still try to not receive slippage on your orders.
1. Trade small volume
It is important that your broker can secure a liquidity at the tightest spread they offer for your order. If the order volume is higher, it is more difficult for the broker to get the enough liquidity.
2. Trade major symbols
Liquidity is more deep when the symbol itself is traded often. Especially EUR/USD/JPY/GBP are the most traded currencies, thus there is much liquidity.
3. No news time trade
During the time economic news is released, the market volatility could be higher than normal hours. In those hours, slippage often happens as the price changes quickly.
