Scooby, thanks for your contribution of this robot. I backtested the EA, and it agreed with your 2009 results, the account nearly doubled.

When I backtest the EA from 2005 on the daily EUR/USD, however, the robot loses 90% of the account.

My question, can we possibly add another indicator that suggests a good time to employ such a strategy? Something to filter out the fakeouts?

Thanks again.
You should not read anything into what ST says + or -, I only use it to makesure EA's are placing/closing trades etc. There are many internal bugs with ST which makes it unreliable.

The best way is to just forward test on demo and/or live.

I have an EA which made +76% on a live account from Jun09 to Jul09 but back testing it on ST shows -14% for the same period.

Steve and others will confirm that ST is flawed.

Scooby,

In your Hedging PDF your talk about ''complete'' bars, by this do you mean we wait until the close of the signal bar to trade and if this is the case which TF bar are we talking about?
M15?

Regarding:

Correlation between EURUSD and USDCHF must be negative.

What is the best way to determine this? Is there an indicator that you rely on to make this assessment on a tradebar by tradebar basis?

Thanks,

saintmo
saintmo,

Maybe you can also try this.

NB: The Lime color is EURUSD while the Chocolate color is USDCHF

Scooby, thanks for the reply. I didn't know the Strategy Tester was that inaccurate.

I will continue forward testing the AI robot. Right now I have it on the USD/CHF daily chart.

Close of the EURCHF bar on M15 but you need to makesure the other EURUSD and USDCHF bars have closed too. This is a notorious problem in MT4 as not all currency bars are formed/closed at the same time.

I think someone here did provide a solution to this sometime ago but I cant remember who or how.

You need to calculate the correlation based on the higher TF being 1H.

I am not allowed to share that EA based on its methodology otherwise I will get into allot of trouble with my trading floor.

It does however include many of the combined stratagies I have mentioned on this thread. Just not all of them.

Scoobs,

Thanks for your advice.

Looking forward to forward test this method when market opens.

BTW,I voted 5-Star for this fantastic methods of yours and also many thanks to Steve for all his efforts.

I am not sure what you mean here. Can you clarify this, please?

i've wrote:

"i wonder about spikes when calculating these 2 lines:

if (Bid > Sma200) SmaDirection = up;
if (Bid < Sma200) SmaDirection = down;

as i understand, we have to check the trend ( sma value (0) / sma value (1) ) and not follow a spike in the wrong trend."

So, we can have 3 cases: sma200 going up or down or flat
I don't see in the code when /where you test the direction of sma: i.e actual value vs previous value.

Same question can be applied to "Dog's Bollocks" as it have taken a buy ticket in that case: sma falling & price below sma, so it should only take "sell ticket" when rsi >=70, nothing else.
So, if (Bid>Sma200) with a falling sma, it's a simple false signal and don't mean SmaDirection=up.

Other question with TCF2:
several tests are made: sma direction, slope trend, rsi value and Bid price.
i don't see when / where the bot compute all these tests to take the final decision.

Sorry Steve if i don't understand your logics, maybe i'm not well awake.

Remeber that if your broker is a dealing desk i.e. they trade against you then they are going to get pretty p!ssed off with you running this method as you will be nicking their coppers.

So, expect requotes/offquotes/connection issues.

They will try to employ a wealth of activities to stop you opening/closing all 3 trades at the same time.

I understand now. Thanks. This makes sense and is easily coded. The thing I question is the validity of comparing Sma(0) with Sma(1). Is this not too close to be a valid comparison? Should it not be a comparison with further back, say Sma(3), even 4 or 5, to avoid 'Sma chop'? What do you think?

Not many of us coding mql4 as professionally trained programmers, so we develop individual coding styles that are difficult to read by other coders. I hate trying to sort out some else's coding.

When I coding consultations to several different indis, I like to declare a variable TradeAllowed. Sometimes this is local, sometimes a program-wide genaral variable if I want to use it elsewhere, such as in the screen display function.

Before sending calls to the indis, I set TradeAllowed to true. Any of the indi function calls that reveal a wrong trading condition will set TradeAllowed to false. Once the indi calls have finished, TradeAllowed is left either at the original 'true' or has been set to 'false'. The code
if (TradeAllowed) SendIndividualTrade() takes care of sending or not sending the trade.

With TCF 2, the bot might be sending either a buy or a sell, so the variables are LongTradeAllowed & ShortTradeAllowed. The code block that manages all this is in start(). You will see a code block with the comment "//Trade filters. Work throught them, cancelling LongShortTradeAllowed as appropriate", then a block of code that manages hedging (at least, you will when I put the updated version up), then a block of code with the comment "//Trading decisions", whose code is only executed if the relevant trading is allowed.

Easy, clear and simple. It would be easier, clearer and simpler still if I put each of the blocks I describe above in separate functions and replace each block with a function call. I probably will if start() gets any more complicated. For now, I can read it easily enough.

I have added partial hedging to the TCF 2. I am not certain the code is bug-free, so watch out for insects. Update in post 1.

thanks Steve,

you are right of course about sma: best to compare sma(1) vs sma(2) when trend change, or use iHighest vs iLowest, but anyway we talk about sma200 so it's trend is not so nervous.

ok, i've read several times your codings to try putting my feet into your shoes, but still need apply some more efforts

note: some days, i've 2 left foot, how can i do ?

I read somewhere on FF but I cannot remember where that if you try to enter the 3 orders at once without using a 'script', you will get requotes, pauses,etc like you mentioned.

So, I'm cracking my brain to recall somewhere is that script. Hopefully a coder can come up with a script for entering the 3 orders at one go.

Just incorporate something like this into your EA.

Basically it will hammer their server.

So sorry for asking... which EA are you saying to incorporate the above?

wana ask if anyone has a script that closes all orders any par. I have a script that closes all orders of a pair, which will not be very useful to the 3 scalping way edge, or a programmer can code to close all open orders, if its possible.
