I will be reading the above link thread. They have a powerful way to swing trade.
A new idea to code an EA

The secret to success is revealed at this post

EA based on above post.
back testing shows waiting for five bars to close on a 4 hr time frame is most successful
https://www.forexfactory.com/showthr...7#post11525577
default settings of ea is 4hr 5 bar . you are able to change time frame and choose between 3 and 5 bar or use both

candy, you had been steady and steady to achieve the success in forex journey. i hope more people can test your eas, and share more results for you.

in this forex journey, we never ended. even we had creat successful eas , we still can not stop, we should continue and continue to creat and creat.
forex never stop , and we also never stop.


your links are very useful. swing or short term trading has their advantege. but i think, if you want the swing trading, then you need to consider open orders can not too much. and MM should be better. but currently i only favour short term and media term will be better.

Very true.
The swing Bar 3 _ 5 EA does not do gap position adding.
Like you say steady steady. By being steady steady it has taught me a lot. Here is how.
What happens is i go through various threads on FF. Pick the best strategy and I code. From there i forward test. There is so much one gleans from observing the forward tests done.
This just sharpens you for the next strategy ince that other forward test fails.

Also Ezios i see you do come through to read. Thank you mate.

Basket trading EA, the one in the TE. It adds positions every gap distance

I will add best buy and best sell levels as signals to trade

I see majamivice is still with us, nice one buddie

Here is an update of A swing 3 and 5 bar V2
https://www.forexfactory.com/showthr...8#post11552568
When we have a swing trigger we looking to buy or sell
Unfortunately the earlier version has better back test.
This latest version has various options of being able to choose Hr4 D1 and Weekly time frame.
Kudus to swingman . I copied a lot of code or learnt a lot from the code he did in this indicator
https://www.forexfactory.com/showthr...3#post11549993
The EA is based on this indicator
Note it will be another three months before i begin forward tests on it.
Also you need to read original thread because there is a limited currency pairs that can trade this pattern by dearest simone, my first cousin
married to the world banker,
The following set files seemed successful on this V2 EA.
Enjoy the toy fellow traders

EDIT 09 October 09:00 London Open
V3 posted

EDIt 09 October 18 11:00 two hours after London open
V4 posted with preset file from back testing various options

I forgot to mention all back testing has been done on EUR USD.
Stay green

candy, i had been read your ea code, it is very intensive logic for me. but you really done a good work on it.

Thanks buddie. Truly appreciate your kind words. I wish i could test it sooner.
But will get there.
I must say i have learnt a lot from other peoples coding.
Thats why my EAs will always be freely given.

You saw how there is no gaps.It only opens based on signals generated. Then it closes based on signal change IF the cashupl is in profit.

i need to admit your learning skills is very well , even better than myself.

Hello fellow traders,
A little update with regards to developing a successful Expert Advisor(EA).
I realised one fundamental mistake I have been making in writing an EA is hedging.
The mistake is as follows. I will use a hypothetical scenario to describe it.
Lets say we have a buy signal and a buy trade opens. Later and while the buy has not closed we get a sell signal.
The EA opens a sell trade. I have been saying, in the back of my head , that this is a hedge of the buy. Blunder .
If truly i was hedging the buy on a sell signal , two trades are supposed to open. One trade will be the hedge and the other trade
will be the sell signal. Unfortunately this blunder totally messes with whatever signal system I come up with. No matter how fine tuned the signal or good quality.
This error in hedging spoils it. So been back to the drawing board . Anyways I hope this helps others out there developing EA's

in my opinion when signal buy you have to buy and sell but buy 0.02 and sell 0.01.
when signal buy continues go profit and close all. if signal sell come then sel 0.02 and so on.
i think this is called an anti martingale system. what you think about it?

i am very glad you had been testing swing 3 bar EA ! in my words, if possible , not use hedge is the safe way in long run.

I will code something to what you have said and post for people to back test. Thanks for your idea

nice one

thank you friend. i will be glad to backtest it this will work good in trending pairs like gj if you use a trend following signal.

Here is polished up EA.
Buys are treated as a basket. Sells are treated as a basket.
Trade signals are generated based on the moving average of your choice.
I have attempted to ensure each input has explanation of what it does.
Also only inputs that work are included. Before i had inputs that were not being used still lurking around in the EA.
Now you can carry out optimization back tests to your heart's content on each input.
Enjoy
Sadly from backtesting I have done not all pairs are created equal. I would a good set file for GBPNZD.
When i try that setfile on any other currency pair it would be a flop. Each pair needs its own file. huge work.
MAGA

Here some results of back tests

Here is the set file for the highest profit acchieved
This is updated file i tested it on

My buddy here is OUR toy .
Open the EA in meta Editor go to line 1842 it says
////#############################################The Condition to open a Buy
// if(MarketSellsCount == 0)
// if(MarketBuysCount == 0)
if( MovingLowAverage(FirstMaTimeFrame,FirstMaPeriod,FirstMaMethod,0) >
MovingHighAverage(SecondMaTimeFrame,SecondMaPeriod,SecondMaMethod,0) )
if( Bid > MovingLowAverage(FirstMaTimeFrame,FirstMaPeriod,FirstMaMethod,0) )
{ B0 = MathMin( MovingHighAverage(FirstMaTimeFrame,FirstMaPeriod,FirstMaMethod,0) + (TradeMiniBuffer * 2 / factor),Infinite);
}//this is the price at which the buy should open
///////xxxxxxx_Sell ###################### The Condition to Open a Sell
// if(MarketBuysCount == 0)
// if(MarketSellsCount == 0)
if( MovingHighAverage(FirstMaTimeFrame,FirstMaPeriod,FirstMaMethod,0) <
MovingLowAverage(SecondMaTimeFrame,SecondMaPeriod,SecondMaMethod,0) )
if( Ask < MovingHighAverage(FirstMaTimeFrame,FirstMaPeriod,FirstMaMethod,0) )
{ S0 = MovingLowAverage(FirstMaTimeFrame,FirstMaPeriod,FirstMaMethod,0) - (TradeMiniBuffer * 2 / factor);
}// this is the price at which the sell open
////////////#############################################################
This is the only condition i have coded to open a buy and a sell. Please give me more ideas to code for the conditions for buy and sell signal.

Next can you inspect the code for anti martingale for any bugs . go to line 2129 here is pasted copy

I am doing some back tests and its looking good

I was asked to code the following easy logic
SHORT TRADE RULES(opposite for buy)

1. We manually set the price level by clicking somewhere on the chart
2. Everything has to happen within the duration of one candle
3. Candle opens below the manually set price level
4. If it crosses above by X number of pips and then goes back below for X number of pips, then we enter short
5. Stop loss Y number of pips above the high of the same candle
6. Take profit 3 x SL
7. Max slippage setting
