How can this be made into an EA

Trade options:

Trailing Stop (TS): True or False (on or off)
Take Profit (TP): True or False (on or off)

Variables (six variables):

Var 1: Current Price

Var 2: Current Simple Moving Average (SMA) where SMA length would be user defined.

Var 3: UpTrend Confirm, which would be current SMA plus an X number of pips where X is user defined.

Var 4: DownTrend Confirm, which would be current SMA minus an X number of pips where X is user defined.

Var 5: ExitBuy Signal, which would be current SMA minus an X number of pips where X is user defined.

Var 6: ExitSell Signal, which would be current SMA plus an X number of pips where X is user defined.

Entry Rules:

Buy when Var 1 > Var 3,
and when current bar close is greater than previous bar close and the previous bar close is greater than the close on the bar before that...
Close [0] > Close [1], and Close [1] > Close [2].

Sell when Var 1 < Var 4,
and when current bar close is less than previous bar close and the previous bar close is less than the close on the bar before that...
Close [0] < Close [1], and Close [1] < Close [2].

Only one trade at a time.

Exit Rules:

Exit an open buy when Var 1 < Var 5, or
if Trailing Stop or if Take Profit is "True" and triggered.

Exit an open sell when Var 1 > Var 6, or
if Trailing Stop or if Take Profit is "True" and triggered.


Thank you

Try it out and let me know if there are any changes you would like.

Thanks Cch,

How would you add a trade size variable to the ea that trades an incremental lot size based on available margin...for example:

if the available margin is $100 - $500 then the trade size would be 0.1
if the available margin is $1000 - $1499 then the trade size would bee 0.2
if the available margin is $1500 - $1999 then the trade size would be 0.3
if the available margin is $2000 - $2499 then the trade size would be 0.4
etc etc based on the total available margin before the trade is triggered...
in the above example...
if the available margin is $50,000 then the trade size would be 100.0

Also to be able to ajust the margin required (set by the user) so that if they wanted it to be $1000 the trades would be:
if the available margin is $500 - $1000 trade 0.1
if the available margin is $1000 - $1999 trade 0.2
if the available margin is $2000 - $2999 trade 0.3
etc etc
where in this example going incrementally up
if the available margin is $50,000 then the trade size would be 50.0
and so on

I added position sizing based on Free Margin. It doesn't step in incraments, but rather trade by trade based on the Free Margin available. It is set as a percent of Free Margin. So if you want to trade 1% of your margin you would set PCT_FreeMargin to 1.

Cch,

Thank you. I will take a look and test it out this weekend. By the way, you write very clean looking code. Excellent. Are you a full time trader? A full time programmer? Just wondering.

Thanks, actually I am both. My failed attempts of manual trading have kind of forced my hand with this programming stuff.

Cch,

Your money mgmt add on seems to work fine.

However, I modified some of the money mgmt quote and half of the logic is working, but the ea is getting stuck with the other half and is not able to trade when free marging exceeds 999.99. I think it is getting hung up on the lot size with an extra decimal point. Is there any way to limit the output to one digit after the decimal point for mini lots? Here is the code...

///////////////////////////////////////////////////MONEY MANAGEMENT
{
double Lot = PCT_FreeMargin / 100;
if (AutoMM)
if (AccountFreeMargin() <= 999.99) Lots = 0.1;
if (AccountFreeMargin() > 999.99) Lots = NormalizeDouble(AccountFreeMargin()*Lot/500.0/(MarketInfo(Symbol(), MODE_TICKVALUE)),2);

}

////////////////////////////////////////////////////////////////////////////////////////////////

Cch,

The one I posted only worked until the EA had over $1000 in avail margin. Once it hit that threshold it stopped new positions.

I modified it again and it seems to be somewhat working. Here it is...it is scaling lot size for every $500 in available margin...

///////////////////////////////////////////////////MONEY MANAGEMENT/////////////////////////////////////////////////////////////////
{
double Lot = PCT_FreeMargin / 100;
if (AutoMM)
if (AccountFreeMargin() > 999.99)
Lots = NormalizeDouble(AccountFreeMargin()*Lot/500/(MODE_TICKVALUE),1); else Lots = 0.1;
}

////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

(MODE_TICKVALUE),1 Seems to control the decimal point of the lots, where 1 is one digit after decimal for standard mini lots and 2 is two digits after the decimal.

I'm sure there is a much cleaner way of doing it, but here is a simple way.
When I get the time I will try to figure out how to have the lots step relate to Free Margin at any level rather than these predefined levels. You could change the values in the code to whatever you want, or add more levels to it. The other problem with this code is the first trade it enters, it uses the default lot setting in the external variables, after that it works fine.

Delete : extern double PCT_FreeMargin = 1.0; (it has no use now)


Just replace the original if (AutoMM) with this;

{
if (AutoMM)
if ((AccountFreeMargin() > 0.00) && (AccountFreeMargin() < 999.99)) Lots = 0.1;
if ((AccountFreeMargin() > 1000.00) && (AccountFreeMargin() < 1999.99)) Lots = 0.1;
if ((AccountFreeMargin() > 2000.00) && (AccountFreeMargin() < 2999.99)) Lots = 0.2;
if ((AccountFreeMargin() > 3000.00) && (AccountFreeMargin() < 3999.99)) Lots = 0.3;
if ((AccountFreeMargin() > 4000.00) && (AccountFreeMargin() < 4999.99)) Lots = 0.4;
if ((AccountFreeMargin() > 5000.00) && (AccountFreeMargin() < 5999.99)) Lots = 0.5;
if ((AccountFreeMargin() > 6000.00) && (AccountFreeMargin() < 6999.99)) Lots = 0.6;
if ((AccountFreeMargin() > 7000.00) && (AccountFreeMargin() < 7999.99)) Lots = 0.7;
if ((AccountFreeMargin() > 8000.00) && (AccountFreeMargin() < 8999.99)) Lots = 0.8;
if ((AccountFreeMargin() > 9000.00) && (AccountFreeMargin() < 9999.99)) Lots = 0.9;
if ((AccountFreeMargin() > 10000.00) && (AccountFreeMargin() < 10999.99)) Lots = 1.0;
if ((AccountFreeMargin() > 11000.00) && (AccountFreeMargin() < 11999.99)) Lots = 1.1;
if ((AccountFreeMargin() > 12000.00) && (AccountFreeMargin() < 12999.99)) Lots = 1.2;
if ((AccountFreeMargin() > 13000.00) && (AccountFreeMargin() < 13999.99)) Lots = 1.3;
if ((AccountFreeMargin() > 14000.00) && (AccountFreeMargin() < 14999.99)) Lots = 1.4;
if ((AccountFreeMargin() > 15000.00) && (AccountFreeMargin() < 15999.99)) Lots = 1.5;
}

Cch,

I thought of doing what you did below but found a way that offers step increments, and allows changing the amount of funds required for each incremental step...for example each $500 or or this case $300 after testing different increments....take a look, it seems to work well...comments? This mm strategy works kind of like a modified REVERSE MARTINGALE where the size incrementally increases with profits and gains and incrementally steps down with losses, so that runs of winning trades are maximized and runs of losses are minimized in addition to using stops and/or pre defined exits....ps#2: would not have even guessed where to start on this code without your help. thank you much...

///////////////////////////////////////////////////MONEY MANAGEMENT/////

{
double Lot = PCT_FreeMargin / 100;

if (AutoMM)

if (AccountBalance() < 600) Lots = 0.1;
if (AccountBalance() >= 600 && AccountBalance() < 900) Lots = 0.2;
else Lots = NormalizeDouble(AccountBalance()*Lot/300/(MODE_TICKVALUE),1);
}

Hi Cch,

I have a simple scalping system would like to turn into EA, would you be kind enough to give a helping hand? Perhaps you can take a quick look first, if you interest I also have some details wants to apply to it to avoid most (if not all) of the fault entry.

Thanks in advance

you may contact me at LGYGT AT HOTMAIL DOT COM, the minute before I send this message my pm is still not working yet (sign up 24hrs ago). Sorry for hijacking this message.

I tried that adjustment you made to the MM, and I could be wrong, but it seems like the Lots won't step once you are above the range you have defined. Well anyway I hope it works out for you.

Dear Cch,
For some reason I can't send pic or file over pm,
I'm sorry that I forgot to post indicators that's need, I will attached at this message, by the way the Sweetspot is always a line land on certain price, e.g. *.**00, *.**25, *.**50, *.**75 perhaps that can give you some ideas.

OR

Do you think use S&R break thru to replace sweetspot, will that be easier?

For buy order:
1. signal has to be below the bright light blue line.
2. macd (5,34,0) must be in the light green area (up tread of positive side)
3. signal bar must drive up from bottom and cross the resistance line (order may place place 3 pips after cross no need to wait for bar to finish)
4. TP is 20
5. SP is 20
6. Chart must look up trend can't not use signal after "red" line

(Check with the pic below)


For sell order:
Everything reverse from the buy order.

Additional:
I would like to have the screen to adjust
1. number of open trade per pair and total open trade of the account.
2. lot size


Thanks a million..

Jason
