Modify an existing moving average crossover EA
We need two things to be done in our existing and functioning EA for MetaTrader 4.
1. Adding a feature that offset losses
2. Adding brokers’ commissions cost to the EA
1. Offset losses
The existing EA, buys and sells as explain on the document attached, called “moving average strategy”.
Our intention is to add a feature that is triggered when a trade make a loss. The objective is to cope with the losses generating more trades, a kind of “Martingale strategy”.
Bullet points
· The strategy tries to offset the loss trades, generating more trades.
· It can generate one or more trades to cope with the losses of a trade.
· We may want to generate more than one trade to cope with the losses of a trade.
· Those trades that are generated to offset loss trades, can generate more trades. In classic martingale, your next trade will try to cope with your previous trade loss, here we will divide in X trade to cope with the loss.
· Be able to choose how many trades are open every time.
· On report, we will need to be able to see how many trades still to be open. So, it needs to save information of pass trades and pending trades.
Parameters
Loss trade divided: 0 means the feature is off. 1 to XX, it will divide the loss trade in XX future trades, if parameter is 5, it will generate 5 consecutive trade to cope with the loss.
Active trades: At some point we would like to choose how many trades the EA opens. If 0, unlimited if above 0 whatever it says. With this parameter you limit the trades the EA generate every time, as market conditions could make the EA to generate lots of trades in a matter of MA crosses.
On report
On report we need the following figures;
Number of trades still to go in case we limit the active trades.
Value of the trades to go.
Number of trades trading.
Value of the trades trading.
Sum of commissions.
A compressive case
See on photo attached, 3.png
First column, called CROSS, this is when a MA cross the EA generate an order.
Second column, called profit main trade, it is simple the main trade the EA does when MA crosses, to make it easy I choose take profit on 4 pips $60 and 40 pips $600.
Third column, called loss trade trigger is a reference of each main trade that goes to losses.
Then the one called profit and loss, is a simple sum of each trade.
And the last one equity, this is the net deposit.
Those this exemple we hae used this parameters
Loss trade divided by: 10
Active trades: 0
So, it will dived the losses by 10 and it will allow the EA open as much trades as the MA and losses dictates.
1. Cross 1 goes wrong and loss money, $600. The EA will generate 10 trades for the next Crosses to cope with loss of Cross 1, and the calculations for the next 10 trades goes as follows $600/10 + target profit / 10. This trades is 1.1.
2. On Cross 2 the EA will generate two trades, the main one and a second one that tries to cope with losses of trade on Cross 1, trade 1.1.
3. Cross 3 the EA will generate two trades, the main one and a second one that tries to cope with losses of trade on Cross 1, trade 1.1.
4. Cross 4 the EA will generate two trades, the main one and a second one that tries to cope with losses of trade on Cross 1, trade 1.1. As it goes wrong, the EA will generate trade 1.2 and 2.1, those two trades will try to cope with losses of trade 1.1 and main trade of cross 4.
5. Cross 5 EA wil generate 4 trades Main trade plus 1.1, 2.1 and 1.2.
2. Adding brokers’ commissions cost to the EA
We need a parameter to be able to define commissions. 0 means no commissions, and then euros per lot.
