Turtletrading EA - request for developmental help

Hello,
I just read the book "The Complete TurtleTrader" and thought I should test it out. So I've started making an EA for it. Now, I know basic C and C++, and just started going through the MQL4 book, and I have put together this little EA.
I'm having some problems with testing this EA though, and keep getting OrderSend error 138 (Requote). I can't understand why this is, especially since the strategy tester should be running on historical data. Error 138 is an error from the trade server (according to http://docs.mql4.com/constants/errors), and the trade server should not even be involved with the functioning of the strategy tester, right?
Having said that, I reiterate that this EA is nowhere close to being finished, and still requires a lot more functionality before it includes the rules required by the turtle trading system.
So, I've added the source code for the EA (named Breakout), and have licensed it under the GNU LGPL v3, so there is no problem with anyone using or distributing it.
Thank you,
Ravi Desai.

It looks like things are out of order in the OP_BUY and OP_SELL part.

Should be
Ticket = OrderSend(Symbol(), OP_BUY, Lots, Ask, Slippage

See http://docs.mql4.com/trading/OrderSend
Take a look at MetaQuotes' MACD Sample EA that comes with the platform.

Oh, wow.
That was a really stupid error on my part.
Thanks for setting me straight, nvwine.

Hello,
So, I've fixed that error of mine and a few others that popped up.
Now we have a system that follows some of the turtles' trading rules. There are still things to address concerning risk management and rules for trending.

Things to do.
-Have to set up a money management system
-Lots should be sized according to market volatility and account balance
-Maximum risk per trade should never be past 0.02 (2%), or can be specified by user
-Lot size should therefore be = (0.02 * account balance) / (2 * ATR(period)
-If the account balance drops by ten percent of the initial balance, the total risk to take should fall by 20%
(from 0.02 to 0.016).
-If the balance rises by 10% (of the initial balance), raise the total risk per trade by 20% (up to a
maximum of 0.02).

-Have to set up no-continuation rule
-If the past 'period' bar gave a buy signal, do not buy on the current bar if it gives a buy signal
-Likewise for sell.

-Have to set up a better selection procedure for finding if a current trade is still on.
-We need a system that will not enter a trade if there already is an order in the system _for_that_same_symbol_, _by_the_same_EA_.

-Have to set up the follow-a-good-trend rule
-According to "The Complete TurtleTrader", we should not set takeprofit values.
-When a trade goes in our favour by (1 * Atr), we should add to that position according to the lot size function, set the stop at the (2 * ATR) point, and bring the stop loss point of the first contract up to this second stop loss point.

I'm not quite sure why you're going through the effort when it was already done for you.

Thanks Ronald Raygun, I tried searching for something like this before I started coding, but I guess there is more I need to learn about google.
I've actually offered to help the other coder with his/her program. Lets see how that goes.

Again, thank you.
Ravi.
