Martingale EA

wolfe · #1 (**permalink**) 01-10-2008, 11:48 PM

A few days ago I received a PM to code an EA with the following parameters:

-User decides initial trade direction (let's say long) and starting lot size (say .1 lot)
-New position would be added every time the market moves x pips (say 10 pips) up or down away from the most recent position taken. If market moves up from the original position 10 pips a new long is added. If the market moves down 10 pips from the last position a short is added (basically following the market looking to catch a trend in either direction).
-Each new position size increased by x (ex: .1 lot)
-Take profit based on account %
-Stop loss based on account %
-Max number of standard lots before EA can't taken any new positions (at this point the T/P or S/L will need to be hit when max is reached)
-Re-enter mode would start a new progression again once the prior progression has ended do to T/P or S/L being hit
-Magic number to run on multiple pairs

I did my best to code such an EA.

PLEASE read ALL the comments in the code to understand the external variables. Default settings are just a guess, testing and optimization needs to be performed.

I'm not sure if this strategy is viable, these type of experts can get you into trouble quick! So use for testing only!

Edit:If you are new to this thread, the latest version is posted below. This is the eighth version I have made as a result to this thread. Please read thread thoroughly to fully understand this EA.

Enjoy.

Explanation of external variables:

PHP Code:

extern int     Bar_Timeframe=60;//Bar Timeframe used to look back on, 1m=1, 5m=5, 15m=15, 30m=30, 1hr=60, 4hr=240, 1d=1440

extern int     Bars_Look_Back=1;//number of bars looked back at from current bar for high and low

extern double  TSLoss_Percent=50;//%Percentage of your HIGHEST profit you can lose before close all is performed   

extern bool    Close_By_Percent=false;//If true it will close by percent, if false it will close by Profit or Loss in $$

extern double  TP_Percent=5;//will take profit if profit is greater than percent of account balance (close all orders)

extern double  SL_Percent=10;//will stop loss if profit is less than percent of account balance (close all orders)

extern double  Close_By_Profit=5;//close if >= to this $ amount

extern int     Slippage=5;//slippage for ordersend command

extern int     Number_Of_Tries=5;//Number of tries to send an OrderSend()command if not going through

extern bool    Sound=true;//if true a sound will be played when an order goes through, and when a close all is performed

THIS IS STILL A WORK IN PROGRESS, STILL WORKING OUT ALL THE BUGS!

Latest version (v1_8) is posted below.

Please explain a little more. if one uses the e.g above.

long at 227.00 1 lot
price goes up to 227.10, enter 2 lots
then price up to 227.20 enter 3 lots
if price were to retrace from 227.20 to 227.10 would you enter
4 lots shorts or 1 lot short?

thanks

You would enter 4 lots short. You should probably start with 0.1 lots or 0.01 lots. This could increase in a hurry.

I just tried to code this EA the way it was requested.

Do you have a better idea?

Hello Wolf...this is very similar to the BlackBird EA...I noticed you have not added the reenter mode yet...but I understand this is a work in progress..The open architecture that you use makes this very versatile...

I did my best to code such an EA.

The expert I made uses a .mqh file that must be saved in your include folder.
The expert WILL NOT function without it.

All are welcome to critique or improve the code I wrote. PLEASE read ALL the comments in the code to understand the external variables. Default settings are just a guess, testing and optimization needs to be performed.

I'm not sure if this strategy is viable, these type of experts can get you into trouble quick! So use for testing only!

The EA starts by using a EMA for initial long or short starting direction. Just an idea. Maybe someone has a better idea?

Enjoy.

Wolfe,

Is the initial entry based on the close of a candle above or below the SMA or does it just need to touch it from above or below? Thanks again for the EA. I hope testing is a success.

Thanks,
lcfxtrader

The EA will re-enter automatically when either a S/L or T/P is executed based on percentage of account balance.

Yes, this is still a work in progress. Any ideas are welcome.

Right now the EA is coded to follow the close of an EMA.

All it does is this: It takes current bar EMA and compares it to close of 1 bar previous. If current bar is > than previous bar it will start long. If current bar is < previous bar it will start short.

If there are any other ideas we could try them.

Hello Wolfe,

Thanks for this EA, this is nicely programmed with Useful info displayed in Journal.
I think you should not really increase your lot as you follow the trend especially starting with 0.1 and 0.2 and 0.3 as you will be really quicly in Loss if the market turn only a few pips.

I think you should start pyramiding with 0.1 Lot only at the begining at least. 0.1 0.1 0.1 etc.. then maybe increase.

Here is 1 of my preset file that you can try in the strategy tester and load for GBP/USD 5M 50000$ for this month only.

Thanks,

Thank you for the compliments sunwest.

You could set the Lot_Size_Increment in the external variables to 0 to not have the lot size increase.

As for maybe increasing, when do you think that should happen?
