If you get bad results then you have something set up wrongly but we can't help you unless you give more details.

Hi Geoffb65,
I was making a manual backtest. And I see that chart, according to the rules it's a correct entry point, both SMA are up between 23-00 (i'm with alpari +2GMT). But in your Report there is not a trade for that day. Am I wrong?
The trade was 2010.04.06 at 01:00

TP1 14, TP2 50, TP3 100, SL 130, TSL 14. ( everything +100 ( 5 digits broker FxPro ), that means TP1: 140 etc. ...)
You do not multiply everything by 10 for this EA!
But please check your broker GMT offset!
Incorrect!

That's right, the EA already takes care of 4/5 digits brokers for you: all input values are in PIPS, whatever broker you use.
TP1 set to 14 means 14 pips.
140 means 140 pips.
BTW running backtest with MT4 during the week-end (= markets closed) makes it use VERY HIGH SPREAD values: i get 8.1 pips spread currently during the week-end with Alpari on GU... (81 "points", Alpari is also 5-digits)
Where the usual typical range is 0.6~1.5pips during the week.
As far as i know, MT4 does not know how to determine the real spread during backtest, so it simply uses the "last known" spread value...
So you get 8pips spread when running backtest during the w-e, and only 0.6p when backtesting during the week days.
That will make a HUUUGE difference in backtest results!
Well, unless there is an option (that i don't know of) that would allow to force the spread value for backtesting purposes, which would be nice...
If anyone knows how to do that, i'd be very happy to know about it!

I haven't tried it because I do enough testing during the week and look forward to a couple of days off!

The EA uses the quoted Ask and Bid prices to generate the order but I have had occasions where a 4 digit broker (TDFX) quotes 5 digit prices, so when the EA uses these to generate the order it is rejected!
This could be because TDXF are STP so the prices quoted come direct from the market as 5 digits but it is a problem!
Regarding the 4 or 5 digit case, I have a question that you may know something about.

Ask and Bid are prices, so are not expressed in pips or points or anything else but just the currency itself.
So it does matter using 4,5, or 6 digs brokers: Ask and Bid will just have 4,5, or 6 digits after the coma: 1.5123 or 1.51234 or 1.512345 for instance.
What can make a difference is the slippage, which is expressed in "points", and THAT will be different between 4,5,6 brokers: a slippage of 3 pips should be sent as 3,30, or 300 depending on the broker.
A slippage value of 3 on a 5-digits broker will be actually 0.3 pips only, and 0.03 pips only on a 6-digits broker, and that has a much higher risk of being rejected.
When opening orders, the slippage value should take care of this.
The EA uses a fixed slippage of 5, meaning 0.5 pip on 5-digs broker.
If the intention was to set it to 5 pips, then the EA should be changed to use 50 instead.
You can change it to be "5*Poin/Point" to solve this.

Hi Geoff, Thought I should stop lurking and say hi.
I'm new to EA's and have never even tried to use one before! After reading this and your other thread I am very impressed with the results and the way that you have presented everything and answered everyones questions.
I'm so impressed, that i am going to put this on my demo (alpari uk) tonight! I'll keep you upto date with the results.
Keep up the great work

5*Poin divided by Point
=5*Poin/Point
You use "Poin" to express the pip value; (i call it "pip" in my EAs, so there is no confusion)

Where do you get so much knowledge of MT4?
