hi fellow traders, i am hemant. i noticed that when Non-Farm Employment Change data relased yesterday ... that hourly candle of FXCM(UK) moved almost 35 pips more than that of alpari(UK).

Why did this happen? all the other times price feed is almost same.. but why different this time? is this usually happen during news release time ? or WAS THAT DONE INTENTIONALLY TO CHASE STOPS OF MANY TRADERS?

I am a novice to this market.. but is this what a good(or bad ) broker do.
Please share your thought on this and guide many new traders like me.

you can look the both pictures attached to see difference...

Are those demo accounts? You might find that the quotes on demo are not as reliable or as accurate as quotes on their live servers, especially across data like NFP.

I don't have an FXCM (UK) live account but an Alpari (UK) live account chart is below...

Open 1.06463
High 1.07453
Low 1.05621
Close 1.06972

Maybe someone else has a live FXCM account?

It might be worth you opening a live account, you don't have to trade it

Who cares about the inital NFP spike...not filled at the correct price. If you're trading that IMO you're gambling. Why trade NFP anyway? Unless trading arb opp's no point in messing around with it. Anyways good luck in your gambling venture. Apologies if I'm a bit harsh, but trying to figure out how to play NFP doesn't make sense to me...unless you have insider info...but if you did, you wouldn't be posting at FF.

Forex is traded OTC..... the brokers do not have common client orders....... it is easy for them to differ in price when there is volatility...


When observing prices. you have to watch the price of the broker you deal with.. not the others who are trading unrelated to each other.

Thnaks pipmutt, FxChi , Blaiserboy for reply..

Pipmutt--Yes those are the quotes from demo accounts.. i guess u are right that quotes from demo accounts are not as reliable as live ones. i better open a live account soon..


FxChi- I know trading at NFP is like gambling.. but those big spikes matter to a trader who is already in a trade one or two days earlier and has a stop loss which might get triggered due those ( intentional ) spikes. thats all the point i want to make here.. any way data from demo accounts are not reliable. so if anybody has an account with FXCM (UK) can post here so we can conform on this ..

Blaiserboy - yes from now on i should worry about my broker only. But it was just a comparison on how various brokers have a different quotes while NFP.

Now I see why you were asking the question. My advice would be if you're in a profitable trade b4 NFP, book the profits and again, don't gamble on the release. Unless you're a position trader, in which case, your stops most likely won't be coming into play.

Now, the question about gunning stops...hmmm...I watched the NFP release intently on E/U. I wasn't watching the price movement at the right of the chart like 95% of most traders would do. Instead I was watching the left part of the chart and watching the ask line move up the chart. 4390 to 4410 was the pivot zone for price last week which is what I watching. Funny that someone drove it right up into there before sinking it. I don't think it was chasing stops necessarily. I think it happened for two reasons..1) Larger traders want the best price to short so they drive up the market. 2) Capture smaller traders on initial spike up knowing full well they intend to short market, and once smaller traders take the initial long position, and larger players short, increase downward pressure and thus profits.

Anyways, last bit was a random rant. Blaiserboy is right though...I'm sure the majority of brokers will have different quotes at NFP due to the volatility.

What about demo feeds? I have been looking at quite a few brokers to try and evaluate there data because I also have seen huge differences. I have one live account that is not MT4 but use it for reference and have not found a demo account that compares 100%, or even 90% really.

Its not just around news events, it happens every hour. Sometimes it seems like the data is delayed by a minute or two. Others have 2-5 pip gaps between close and open of bars. Still others, time chunks of data are missing.

So far no two are exactly the same. What I'm asking is if you have a live account could you confirm that the data is different on the demo account?

Thanks

A minute or two, and missing data! That doesn't sound right, are you sure it's not a connectivity issue?

You'll probably see small disparities between brokers and between demo and live, some demo quotes are not updated as frequently as live, but you shouldn't really see any big differences. Although retail forex is OTC most of these shops derive their price feeds from the same sources.

I think it's useful to have a second price reference other than your broker's, maybe trade on their platform but use someone else for charting.

I have at least 5 demo accounts and I'm trying to make sense of it. I have one account that seems to draw one minute bars slightly behind other brokers. Maybe 1 to 2 mins is an exaggeration but it is defiantly 30sec to 1 min. Another broker had a huge gap down. I was watching the chart at the time and looked at my live account which showed only an orderly drop in price. I reloaded the data and the gap was still there. I attached the chart look at the times. Almost 2 hour gap! The gap did not occur with any other broker. I have two machines running and the gap occurred on both.

After posting that I had a thought; look at the 1 min charts. The 1 min chart does not show those gaps. Very odd.

I don't know enough about MT4 to give you any accurate advice but it sounds like a connectivity issue or corrupt data (have you looked at the connection history in the Journal tab?), what's odd is that the missing data isn't filled in when the platform reconnects.

Maybe give the broker a ring or email them, they'll probably know what it is straight away!

Hi hemantaims,

Here's a screenshot from the independent Comstock data feed aggregator which provides an indicative feed for comparison. Low on USD/CHF Comstock feed from NFP was 1.0584. This data feed can be accessed here . While this feed is indicative, it will give an independent view of where the market traded.

FXCM's no dealing desk price feed is made up of 10 banks and the best bid/ask price from the 10 banks is streamed through to the platform.
