EA Programming Questions ???

Hi all,

I am new to EA programming ..... though i have clocked a number of years in C, C++ and Pascal programming.....

One of the thing i noticed was that the Strategy Tester by Metatrader uses Open Prices for its back testing. As such the EA will also base its Entry and Exit on this Open Prices.

Is there any way to based the EA Entry & Exit on the Close Price instead? I feel that this result would be more accurate since we usually enter a trade based on the previous bar's Closing Price rather than the current bar's Open Price.

Thanks for any advices in advance!!!

where the ea looks for its decisions is up to the programmer. If I choose to look at the previous candles close for my decision do I not have to wait for the new candle to form prior to the previous one being completed? Which in fact would make the EA open a position at the current open price.

Thanks magnumfreak. I get what u mean.

Initially, after doing a run on the strategy tester, using an entry like

If (Signal_Current > 0 && Signal_Previous1 < 0)
Enter Order

I found that it is not 100% acting on this instruction. There are misses where there should have been entries, or entries where there shouldn't have been. I thought that this issue should have been caused by where the Current Bar's Open & Close pricing is.

The EA acted on the Opening Bar price. But what we see plotted on the indicator chart is the Closing Bar price.

I did a retest using a formula like this
If ((Signal_Current > 0 && Signal_Previous1 < 0) || (Signal_Current > 0 && Signal_Previous2 < 0))
Enter Order

It seem to achieve 99% accuracy.

Hey guys! I am also new to EA programming and have been trying to calculate Weekly Account Profit and display it on my chart with no success. I can use the Comment() function fine, but have not come up with the proper code for calculating Weekly Profit. I have used AccountProfit() and OrderHistoryTotal() functions, but it just does not seem to work. Can anyone help me?

on sunday night or monday whenever you start the week, copy the account balance to a global variable (look under globalvariableget, globalvariableset). Then at the end of the week compare the current balance with the one saved in the global variables.

Make sense??

Yes, conceptually it makes sense, but trying to code it still baffling to me. Where would I begin. The EA have coed so far is very, very simple. My goal is to evenualy have the EA halt trading after it reaches a Weekly Profit/Loss Threshold, but I can't begin to try that without having the calculation coded. Can you provide the code that uses the globalvariablege, globalvariableset functions, please? I completely lost and frustrated. Thanks.
