{quote} I have seen some brokers widen spreads to 30+ pips (300 points) so in that case it would be better to set MaxSpread
Thanks for the tip Alan!
As opportunities are rare, it does not make any sense to trade less lots, so maxspread really helps to avoid losses if the impact is not as strong as expected.

Let's talk a bit about Slippage. It is almost always present during a big news, such as NFP and it normally increases as the traded lots are much more. I mean, I can see a 5 pips slippage on a 0.01 lots trade but the same one with 2.00 lots can have 20 pips slippage or even more.

Apart to use the specific setting that controls the slippage ("SlipCheck=true", that I don't like to use because I am looking for a 50 pips trade and 10-15 pips of slippage are uncomfortable, horrible and indigestible but this is "the game"), do you have any ideas how to face it?

This is my personal understanding of slippage:

It happens with big movements as the new chunk of information about the current price (a "tick") that comes in is substantially different from the previous information about the current price. I understand it as a "gap" inside a candle, but you don't actually see it as you do with separate candles.

So if you chose market execution, your broker is obliged to execute your orders at the next best available price, which might result in a slippage on big movements (otherwise you would have received a requote - with "instant" execution).

I also believe that it should not depend on the size of your order, this is strange. Theoretically it should mainly depend on the liquidity provider of your broker, meaning more liquidity = less slippage.
As you said, slippage is part of the game, something inevitable, so I guess you just have to accept the risks.

I am very impressed with this answer. I think you practically nailed it. One of the reasons the EA saves an AmazingEA-Tick file is to record the prices for about a minute before to a minute after the trade. So you can review exactly what happened re Slippage etc.

There are 2 places you can get slippage. The first is during the pending order phase. Let's say EURUSD trades at 1.10 but a news event comes in and you have a Pending Buy (a.k.a Buy Stop) order 10 pips away at 1.10010. But let's say price gaps up to 1.1005 initially but then jumps to 1.1020. As soon as price goes past 1.1010 your Pending Order becomes a Market Order. Now the size becomes slightly more important. At 1.1020 there may be many Pending Orders to be filled so price may climb to 1.1025 or 1.1030 before everybody is filled. As wizardaram8 said, this is a factor of liquidity.

Now an ECN broker will only fill you if their Liquidity Provider agrees, but a Market Maker broker may choose to fill you earlier even if they haven't got liquidity. They are willing to fill you but will trade against you or prevent you from withdrawing. Why do they do this? Because they don't have as many proper price feeds or 'Liquidity Providers'. Remember they are trading against you - their aim is to make you lose. So they will try things like freezing the server, spread spikes or pointing to a little recognised condition in their Terms.

Personally I prefer to trade with an ECN. The other thing is that when you get slippage, price is normally headed in that direction anyway which is why there is reduced liquidity in the first place. So although slippage is not welcome, as long as you don't get stopped out because of it, your trade will normally come right eventually.

Thanks for uploading your logfiles. So the major problem was that the Settings File wasn't copied into MQL4\Files. You need to check the bottom line ReadSettings=True and which SettingsLine the EA has picked up.

Therefore the EA used Default Settings which are ok for most events but not loose enough for NFP to give your trades enough room. Some triggered early in the wrong direction. Also you had too many trades going at once (was it 5?) although there weren't any errors - I would say stick to 2 max initially per MT4. The MT4 may not be able to modify the Pending Orders fast enough if you have many trades going.

I would also steer clear of GOLD and EURUSD at NFP. They are both prone to dodgy price spikes. GBPUSD, AUDUSD and USDJPY are safer. In fact many JPY pairs used to be preferred for NFP.

So I just uploaded an updated Settings File.

I copied the AUD Cash Rate entry and called it AUD RBA Rate Statement.

The reason for this is although Cash Rate is listed above RBA Rate Statement in the Calendar, the special page that the EA uses has them listed the other way round which is why the EA is showing 'RBA Rate Statement'.

So to get the EA to pick the correct settings please download the latest spreadsheet from the first post.

Hello, Alan!


I'd like to test your indi for the 1st time on demo account.


To be honest, I find the installation instructions a bit unclear:

1. Why the "AmazingEA Installation" part is put in "TroubleShooter" file? Maybe There should be separate file for it?

2. The default settings of indi say that Settings are to be load from file, but the instruction doesn't say to put both "AmazingEA-Settings" files into MQL4\Files. I can see that caused troubles for zotya130.

3. What to do with the file "AmazingEA.set"?

Hope this will help to make instructions better.


Also I download the latest "AmazingEA-Settings" files you uploaded 2 hours ago, but the indi still shows RBA Rate Statement as the news title (see screenshot). Is this right?

Thanks in advance for your reply.

Andrew.

Hi Andrew

I appreciate the feedback you provided.

The reason I put the Installation in the Troubleshooting file was originally because most people know how to get the EA running so would only need help if things weren't working but you are right I will make a separate Install File.

It's only the latest version that loads from a CSV and the instructions need to be improved to be a bit better to help people. So the AmazingEA.set was there from a long time ago (before the CSV) to show that you could save your settings. I should probably remove that and the 4 digit settings and just add that information to the ReadMe files.

Yes, the title RBA Rate Statement is correct. You see how it says SettingsLine 004 - that means it's picking up the settings from the 4th line in the CSV

From your second post, now you have nothing on the screen what does it say in the Experts tab? Either revert to the original Settings file and load the EA again or if something is still not working, send me your logfiles

Hi allan, 
 
I tried it on a demo with pepperstone. On my VPS. 
It immediately closed all the pending orders. What to do?

OK, it seems that your broker has a bit of weirdness in their system. To work out what Lotsize you can use I look up 2 pieces of data. The minimum number of lots and what size you need to step up to. e.g MinLot 0.1 and LotStep 0.1 so next biggest size would be 0.2. To work this out I do this calculation

MathFloor(lot/lotstep)*lotstep;

Your broker is reporting the LotStep as 0 which is causing a DivideByZero error. This is not normal as this code has been in the EA for a couple of years at least and nobody else has reported that problem. I will put in some code to handle this situation and release an update. If you want to try a Demo, can you use a different broker for the moment?

Out of curiosity what did you modify in the XLSX and CSV files? Especially to do with Lots?

Hey Andrew

Scratch all that - especially about your broker returning the wrong value. I lookup the value like this:-

double lotstep = MarketInfo(ActualSymbol,MODE_LOTSTEP);


So if ActualSymbol is not a valid symbol it would also cause the same issue.

I think you made a mistake with the currency pair name when you saved the file

So you meant to put AUDUSD but may have put AUDSUD or something instead.

By the way, you can also use the word Default to pick up the current pair on the chart.

I will add some code to check the Currency Pair is valid and output an appropriate error message.

I think it may be the error caused by wrong saving/overwriting the file.

After I save the file, it looks like in the screenshot. The red rectangle shows my modified parameters.

That should be OK. I don't understand why that would cause an issue.

Would you mind uploading the CSV file here. You may have to Zip it first to allow you to upload.
