What brokers have no slippage?

Oh, my bad. I read 2M but calculated as 1M

Ok.. the answer is... Almost 1 Month of profits! (ta-da! fireworks start firing, orchestra is playing, everybody dances and little 5 year old girl with red balloon in her left hand and ice cream in the right, drops one heavy, innocent tear from her eye..)

I was thinking that broker should have been better if they can implement a no slippage policy, it will be to the traders advantage, I have seen a few broker that do such thing, they will honor your stop loss, entry, breakeven point even at a major news release, even non farm payroll but they never do unscrupulous price manipulation ...so even if the liquidity provider dont these brokers follow what is best for their clients.

You can trade without slippage with Market Makers. DD execution is also full of requotes and the spreads are wider.

Oanda, Pepperstone, FXCM, FXPRO. There's no "no slippage", there's "RARE" slippage, can be for your advantage at times, and disadvantage at others.
Fixed Spread brokers must have "Rare" slippage but higher spreads

They always have some slippage.
Some are tighter than others.

No slippage with Oanda, maybe. I've never noticed it. But what you'll notice soon enough if you know what matters in this game is that they have massive spread widening that not only bilks you out of opportunities, but paints a false picture of price history on the charts. In fact I withdrew the last of my funds from them today and switched over to another company because I was absolutely sick of it, and there's nothing customer service can do to help even though they were courteous and generally helpful to be fair.

I guess Kanzler is right Bucket shops :-)

Well the answer to the question is:
Brokers that do not bring the price to market and keep it on their books, will offer no slippage.
On the other hand, Brokers that bring everything to market will undoubtedly slip you in a fast market.

But I do have to note that also brokers that keep your trades on their books (ie: Non ECN brokers) will slip u in a fast and illiquid market. There are plugins that can control this like the Virtual dealer plugin. A few months back I explained this in my blog what the pluging does :

and here is an article of brokers being fined for using the plugin:

Generally B Book brokers or Market-Makers offering Fixed spreads allow for "automatic execution" or 0 slippage (similar conditions to a standard MT4 demo account). Stop-hunting, toxic flow, spread-widening - normal practices here - very cynical in my view.

Unfortunately, slippage (some) should be expected with an ECN, especially if you are trading in large size. To avoid slippage or reduce slippage (more-so for scalpers or big-hitters) you should look to choose a broker with a large ECN LP & get in good with your account manager to make sure your trading conditions are fully controlled!

P.S. Market-depth windows, from experience are becoming more unreliable!

FIFO rules all amongst the larger LPs!

Anyone asking for zero slippage obviously understands not a lot. It is a natural part of the market conditions and any broker offering zero slippage i would definitely stay away from.
