BK's Grid EA (Martingale)

In 2008, I was commission to rewrite a Grid EA based on original EA found at www.forex-tsd.com. More of the discussion can be found here:
http://www.forexfactory.com/showthread.php?t=65249

Back then I could not share my codes as it was commissioned. However, I can now share it.

This EA is best used on brokers offering 0.01 lottage - $0.1 a pip.
Though small lots as it may seem, you will be amazed how much it will trade in a day making $50~$100 each day with a $5K account. I personally used this EA on FXOpen (not recommended) and later on IBFX (recommended).

This EA can be used to Martingale Manage your "manual trades". ie, you manually open a position (buy or sell) and this EA will add positions to average the price.

I also used this EA on Demo account as a Momentum Reversal Indicator. ie, when this EA made a lot of positions on one side, then it is time to manually trade on a Live account against the direction of the trend - think of this similar to a Bollinger Band indicator.

Feel free to ask questions.

Hi ,
I'm new to EA's but ,

I am looking to develop a trading plan which incorporates mean reversion probability in spot forex .
Basically ,my understanding of mean reversion is what goes up must come down ,(vice versa) eventually returning to the mean but never zero .
Unlike a casino game like roulette , where every result is independent and random .
I kind of figured a long-term martingale strategy with 200 pip blocks could work .
eg: buy 0.01 lot EUR/USD with a take profit @ 200 pips and a pending order to buy 0.02 lots in the same direction 200 pips away and so on .

Can you set your own amount of pips with Burger King ?

This EA can do that already.

Just set:
* TakeProfit to 200 instead of default 0 (which has its preset value depending on currency pair).
* MinGridSize to 200
* MaxGridSize to 250
* GridFactor to 0
Try it on DEMO account

For all intents and purposes, the default values, which you will see as "0" has preset values pre-programmed to them depending on currency pairs it will be used. Based on current volatility, the best pair to run this is EURUSD. Be sure to run this NON-STOP on a VPS. If you dont have that luxury, then this is not going to work.

As long as it is running on a machine with continuous internet connection.

Several folks failed on this EA because, they run it on their local machine for a few hours, turn off, come back the next day and missed the chance to exit on their previous positions.

This is why continuous running is a must. If you'd noticed, this EA also include a "WatchDog" wherein it will create a Pending Order and modify the price to match the minute of the hour such that if you are monitoring the account from another machine, you'd be able to tell if it is still running or not. When I last run this in 2009, my VPS suddenly had an emergency reboot. I once knew it wasnt running because the Pending Order Price isnt moving/matched to the current time.

Hi Burger, could you explain about the parameters in your Grid ?
I'm trying to change some of them but can't figure out what they do.
Thx.

BK,

What do you see as the main advantage that your Grid EA has over something like SWB?

I'll explain SWB, briefly, if you're not familiar with it. It is a CTrend system that uses 12 RSI & BBand indies to show OB/OS. I used it, extensively, with a grid range of 25 pips and full martingale lot progression, i.e every 25 pip move, with the trend, doubles up the lot size on your countertrend position(s).

I started to run it in demo just to see the difference between BK Grid and Blessing. From what I see so far, BK Grid will do buy and sell at the same time. It's like running two Blessing EAs (FMC=0 and FMC=1).

Stay Tune

BK. Thanks a lot for opening this thread and making the EA available.

I've started running the EA to see what it does. Some details of the strategy it employs would be helpful.

Usually, it's possible to open an EA's properties box when it is running. For some reason, this one won't allow that.

I haven't tried backtesting as I, usually, find this a waste of time with an EA such as this. I'm running it in on a demo account and have had no errors so far

With EAs that use grids, hedges and Martingale the results, from backtesting, can vary, depending on which broker's data is used. Spikes etc. can skew the results.

I left BK's EA running over night, on EU, and it made about $300. Unfortunately, in this morning's London session it hit max DD and lost $540!!

You cannot backtest. Only forward test on a DEMO ACCOUNT.
It takes more time but it is not an EA that is curve fitted to any HISTORICAL DATA.

Backtesting is not accurate a gauge. This is why you need to run this FORWARD on a DEMO.

On EURUSD Jan 31 to Feb 1?
I doubt it.
Unless you were using it with 0.1 Lots on a small account.
The sweet spot for this is to run it on a $10K DEMO ACCOUNT, using 0.01 lot (default). If you dont have a broker with 0.01 lots, then raise the account size to 100K...

Of course I am not saying you to put 100K and run this EA on a Live account.

The default settings are tuned for EURUSD, GBPUSD, USDJPY, GBPJPY... On today's range, the best pair to trade it on is EURUSD and USDJPY. BTW MaxDrawdown is currently set to 0.01... The Drawdown in % of the account; 0.01 means 1% of the account. I use 0 for no SL, or 0.25 for 25%.

There are other ways of using this EA other that the EA itself. Currently, I use it as a "Momentum Reversal Indicator" similar to a Bollinger Band. When you see it having lots of position on one side (ie, 15~20 BUY positions) then it is time to BUY as the price is ready for a pullback.

At any rate, if this doesnt suite you, move on..

positions on the Buy side, how many would there normally be on the Sell side? I didn't realize one could hold both Buy and Sell positions simultaneously with IBFX.
