Ambler Gambler EA

[anamy]

This is a martingale EA that I made for Gazuz a few months ago. I haven't been able to get a hold of him lately, so I was not able to ask him if it was okay to post the system. Rather than having it sit around on my hard drive, I thought I would post it up on this forum. The following is Gazuz's explanation of the system which I coded:

Buy and Sell X lots (determined by a variable "A") this means we will go in both directions from the beginning, a sort of hedging minus the spread. Set a take profit at X pips (other variable "B"). Once one take profit is reached, for the sake of argument it went up B pips, The close the BUY position, open another one and close the SELL position. Now re-open BUY position with A lots and open a SELL position with A*C lots (C is a variable to mutilply the number of lots by) resulting in having a net profit of 0 minus the spread, instead of just the loss or just the gain. Later we keep applying this algorithm. If the price goes up again B pips, the BUY position is closed with the profit and the SELL position is closed with the loss, we re-open another BUY positionn in intialy lots. Now we open a SELL position with A*C*C (it keeps increasing until that position wins). Now lets assume that the price falls B pips, the sell position closes with a profit and hypothetically should cover the losses plus the intial profit (depending on our C value). We close the BUY position with a loss. This time we open a BUY position with A*C and open a SELL with A. I'll recap it below in less words and more math.

A=1
B=10
C=2

Open BUY position @ 1.2900 with A lots
Open SELL position @ 1.2900 with A lots

Price goes to 1.2910

Close BUY position @ 1.2910, gain $100*A (1 lot = $10)
Close SELL position @ 1.2910, lose $100*A
Open BUY position @ 1.2910 with A lots
Open SELL position @ 1.2910 with A*C lots

Price goes to 1.2920

Close BUY position @ 1.2920, gain $100*A
Close SELL position @ 1.2920, lose $100*(A*C)
Open BUY position @ 1.2920 with A lots
Open SELL position @1.2920 with A*C*C lots

Price goes to 1.2910

Close BUY position @ 1.2910, lose $100*A
Close SELL position @ 1.2910, gain $100*(A*C*C)
Open BUY position @ 1.2910 with A*C lots
Open SELL position @1.2910 with A lots

Price goes to 1.2920

Close BUY positon @ 1.2920, gain $100*(A*C)
Close SELL position @ 1.2910, lose $100*A


Now I think thats enogh I proved my point, using real numbers if we start with lets say $10,000 we would end with:

$100 - $100 = 0
$100 - $200 = -100 = -100
-$100 + $400 = +300 = +200
+$200 - $100 = +100 = +300

+$300
by buying and selling

versus the original of only chosing one side which results in:

Sell only:
-$100
-$200
+$400
-$100
=+$100

or
Buy only
+$100
+$100
-$100
+$200
=+$300

This means whatever way it goes, we will make profit as much as possible and not go as negative as we would in the original Martingale case

As with most martingale, a sustained trend in either direction will hurt your account big time. If anyone wants to test it, I would really appreciate it. You can post up some account statements if you decide to.

Forward tests, please. On multiple pairs, with large TP (let's say 60+).

wrong logic anamy.

"let think buy and sell in the same price and same lot=0".

the reality is instead of buy and sell first, we do not take any position.->same+we don't pay spread at all.
(buy 1 + sell 1= 0)

1.when price goes 1.2910 for the first time, we sell for the first time.
(buy 1+sell 2= sell 1)

2. when price goes 1.2920 , we sell more lot than original bcs:
(buy 1 + sell 4= sell 3)

3.etc

and you will see the result is same+we don't cost spread.

this way if you want compare it with the original one.
+on the original, more margin can be use than this.(this hedging divide margin by two)


i wonder what hedging use for.
