Forex slippage: How slippage happens and why you need a good broker

What to do with forex slippage; how it affects traders

Many students expressed concerns that slippages happened to them during trading when I was discussing about choice of brokers while training the class of Tflow® Forex Course Intake 36.

 

What is slippage?

Slippage definition: A slippage happens when a limit order or stop loss is triggered at a worse price than the originally set price. Forex slippage is very frustrating and one reason for traders to encounter heavy unexpected losses. If you encounter slippage regularly during trading, you may have chosen a bad broker.

The slippage went up to 40 over pips diff.

 

Circumstances when slippages happen

  • time of low volatility (not too much liquidity or trading volume in certain timezone or certain period of time; low volatility usually happens during Asia trading zone or before market opens/closes)
  • release of high impact news (e.g. FOMC meeting minutes)
  • special event (e.g. 911 or Fukushima earthquake in Japan)
  • or simply, your broker decided to ‘slip’ you or play tricks to your price fill
  • or you have dealt with brokers with very few liquidity providers (most of time, this happens when you are trading with a market-maker)

 

Observing your broker’s ability to fill your trade at the right price

Extreme price movement (like when price spike happens) is the best test of your broker’s ability to fill your trade at the right price. This is also the best test to understand how your broker is handling slippages (or whether you have encountered slippages).

Let me illustrate with a trade that happened to me. This was a very good opportunity to test my forex broker’s ability to fill me at the indicated price or even better price.

What happened to me on EURGBP Trade? Filling at good prices

I had a limit order to close my trade for EURGBP at various prices. This means that I have already existing trades that sold EURGBP and I wanted to close my trades at a lower price. So I put in a limit order lower than my trade price. In a limit order, once price quote reached the indicated limit price, this will translate into a market order. Your broker will then fill you at whichever price they are able to get. Therefore a limit order does not guarantee that your order will be filled at your indicated price. Thus slippages can happen here.

At that particular 1 minute bar, EURGBP had a price spike and all my orders were filled accordingly. My broker has more than 20 plus liquidity providers including 2 major banks that can fill my orders.

I have 3 positions that were filled in that 1 min bar.

3 limit orders were keyed in:

  1. 0.8562 filled at 0.8557 (better price)
  2. 0.8546 filled at 0.8543 (better price)
  3. 0.8540 filled at 0.85376 (better price)

Note that all these orders happened in a spike of EURGBP in just 1 minute. The ability to fill accurately each order and even a better price during such a spike says a lot about this broker’s liquidity.

Why is it important to choose a good broker?

Brokers have a natural win rate, as the common saying suggests “95% of traders lose money”. If this is the case, they do not need to do anything to make money from 95% of traders.

However, whether you are losing or making money, it is important to have a forex broker who do not play tricks on you. Why? I always believe that when we lose money, the loss must not be inflicted by others. Let’s play it fair.

Many brokers provide wonderful services and platform, but most of them do not want to admit that they are market makers. There are even worst types, where they claim that they are Straight Through Processing framework (STP), but only a minority of their clients are applied STP. Even you get to a STP broker, how sure are you that you are not B-booked (or placed in Risk-book)?

 

Students’ Experiences

I like to share a student’s account with one market-maker. I have deleted all traces of student’s identity and also the market maker operating in Singapore involved in this email. The main purpose is to let you understand how a slippage can happen to you.
