Bill;

I will fix the stop trading time to 20:00 in the next EA update. As far as the EA closing at the open of the next bar I don't really see a big difference. What I mean is we have to wait for the current bar to close before closing the trade and the best way to determine bar close is to use next bar open. Again I am not a coder by trade and continue to learn. If any coders out there can help with this subject matter it will be greatly appreciate it.

TimeFreedom
TimeFreedom,
I'm sorry, I should have been more specific.
It didn't seem to be closing on the open of the next bar. It was closing on the next bar at a price I couldn't see any pattern to.

Let me try the new one.

Thanks again.

TimeFreedom,

Here is what I've determined, so far.

I visually tested it on EUR/USD. It has a 2 pip spread.

If you are exiting the trade on the Open of the next bar, it is working properly and closing at the correct price.

It is not opening orders at the correct price.

On Buy Stops- It is adding 2 extra pips to the correct Buy Stop price.

On Sell Stops, it is subtracting 2 extra pips from the correct Sell Stop price.

Example- If C of previous bar was 1.3700, it sets a buy stop on the next bar at 1.3705. It should be set at 1.3703

If it sets a Sell Stop in that instance, it sets it at 1.3697.
It should set it at 1.3699.

I hope this helps.


EDIT- The 2 extra pips I alluded to above, is also present on the GBP/USD test. It has a spread of 4 pips.

I believe the exit is correct.
He's exiting on the open of the next bar rather than the close of the trade bar. The ones I've tracked were at the proper price.

I haven't looked carefully at the EA, but from your comments the exits have to be correct... How could you exit at the close (the last tick) of the trade bar? By its very definition, you don't know the bar is closed until you get the first tick that belongs to the next bar. So if the EA works the way you guys say not only it is correct, but it is the only possible way to do it.

Trade made on EUR/USD @16:40 FXDD time

Sold 1 pip below previous close
Closed at the closing price plus spread which was 1 pip better than the open price of new bar.

Just did a Buy on GBP/USD at 1 pip plus spread above previous close

Looks like its right on the money

Awesome....I did something a little different in that I only traded in the direction of what I call my MACD Momentum Builder trades. Yes....I wold have missed out on some trades, but I feel better going at least what I deem as momentum.

I am then also looking at going into a lower TF chart to follow a fast momentum there to see when i should exit, although this is just preliminary at the moment.

On M30 today I was 4 for 4 today with eurusd, 3 for 3 on usdjpy and 2 for 2 on gbpusd....i really don't like trading usdchf in this was and so I passed.

On H1 today I was 2 for 2 on eurusd.

A pretty good day. I will start forward testing the EA on a demo account now as well

Here is a discrepancy using your latest version:

The red vertical line is the end of the 1/05/09 13:00 bar.

The blue horizontal line is the LOW of the 13:00 bar.


1. The 1st arrow shows the new 13:30 bar going below the LOW of the 13:00 bar during its first minute.

2. The 2nd arrow shows price exceeding the CLOSE of the 13:00 bar. This occurred during the 13:31 bar.
The trade should have been entered at this time. The SL should have been set at 1.4476.

3. The 3rd arrow (13:35) should have hit the SL.

At the bottom of the chart is the EA's record during this time.
It shows a winning trade.

It seems to have ignored the activity prior to 13:36.

Hi Damoni,

Could you elaborate on how your MACD Momentum Builder works? 11 wins out of 11 trades is very impressive!

This EA looks very interesting.
I am testing this on FxPro which has fractional pips and seeing a lot of OrderSend 130 error messages in the journal.
Would it be possible to make the code fractional pips aware?

A few changes to the EA to more closely reflect the strat. rules:

Added the following changes:

*Only Trade between 7:00 and 20:00GMT
*Previous Bar Range Needs to be at Least 15 pips
*Fixed SL and TP Function
*Trade Status and Previous Bar High, Low Range Comment Added

Note: Please test and let me know if the EA is trading per strat. rules. Once the EA is trading per strat. rule then we can start to optimize.

Hi,

Wouldn't it be more useful if the chart shows "Previous Bar OpenClose Range" instead of "Previous bar HiLo range"? Since OpenClose is more important..if it is >15 pips, HiLo pip difference wouldn't matter so much.

I am not good at programming ,...If I understood correctly, process flow is more or less (I use BUY example):
1) Calculate Open-Close for bar(1)
2) (may be) compare diff CloseBar(1) & Openbar(0) within xx pips to proceed
3) wait for Bar(0) low falls below Bar(1) low to activate pending buy or just go into ready-to-order mode
4) send BUY order if price is 1 pip above CloseBar(1)
5) Close order when Bar(0) changes into Bar(1) at new tick of Period()

For #5, why dont use the template:
bool New_Bar=false;
if(New_Time!=Time[0])
{
New_Time=Time[0];
New_Bar=true;
}
Once new bar arrives, then close order. Therefore, no need to use time to activate close order.

Some of the above points may be repetition of what being discussed. This is just a rough idea of the whole process. I notice fine tuning/correction (e.g Ask, Bid usage) already incorporated.

Cheers,

Bill;

Please make sure you are using Beta04 which takes account of the external pipsBuffer and not minStopLevel which is adding 3 pip buffer to the trades instead of 1 pip per the rules. FYI, I noticed that using a 3 pipsBuffer gives me better results.

I can't understand what you did.
At Point A, you say "top+1 pip"
You should have been looking for it to go below the Bottom - 1 pip.

I'm almost certain that I was using 4.
I'll do it again, when time permits, and let you know if I get the same results.

The rules clearly state to determine the bar's HiLo range and not OpenClose range. For #5 please take a look at the EA and make changes you see fit and note your changes in the EA. Also make sure to change the EA version when making changes.
