{quote} I don't understand how it's possible that the Target Based is reached before the Middle Point. For instance, if a buy limit is hit and then the price goes up, I seem quite obvious that the price will reach the middle point well before the price target (unless the price target is very small). Could you clarify? Thank you!
It's again quite obvious that the market price could move wherever it wants, am I right? Let us talk about GTLIMITEURUSD2 with v1.7 EA. Remember that v1.7 has positive bug in Middle Point, where it will close the order not at the middle point but when all orders turned positive instead.

Imagine this case,
Middle Point will be reached first if:
- Price movement causing first order to be executed / opened, then the price retracts back and executing second order on the other side. Once all orders are profit, middle point logic will close it.
- Price movement causing first order and second order on the same side to be executed / opened. Once all orders are profit, middle point logic will close it.

Then, Target Based will be reached first if:
- Price movement starts trending and executes (for example) 5 orders, then the price retracts back. Although all orders not in profit, if total profit is exceeding the target based, then all orders will be closed.

Now, why the Middle Point logic doesn't close when the first order is executed?
Because in GTLIMITEURUSD2 set, it has Middle Point trigger. If you set "Middle Point Activation" to 2, here's the logic.

Inserted Code
(((BuyCount + SellCount) >= CloseMiddlePointAftOrders && CloseMiddlePointAftOrders > 0) || CloseMiddlePointAftOrders <= 0) && AllPositiveProfit && Ask <= AskTH && Bid >= BidTH))

It will check whether the total count of opened orders from both sides is more than 2, AND it will check whether all is in profit. The rest is the bug (useless logic).

Now, get back to your case. If a buy limit is hit first, then the price goes up, that means only 1 order executed. In this case, the logic above is not hit yet.
Then the price keep going up, the first sell limit is hit first, but then the price is moving up. In this case, the logic above is only fulfilled one side, this logic:
Inserted Code
(BuyCount + SellCount) >= CloseMiddlePointAftOrders && CloseMiddlePointAftOrders > 0) || CloseMiddlePointAftOrders <= 0

Now, then imagine that the price is moving down a little bit causing both orders to be in positive, then the whole chunk of logic will be TRUE and orders will be closed.
Another case, imagine the price is not moving down, it keeps moving up until the 5th order executed, then it retracts back. If let's say price goes down until reaching again the 2nd order, in this case normally Target Based will reach first.

All of this scenario, you can simulate it on the excel file I've given: http://rdzgridtraps.codeplex.com/releases
Just try to simulate it there.

Bro Radityo, Just wondering why my pending orders isn't closed outside the time range when all my opened positions cleared (no open positions). Never experience this issue before...this is on v.1.7 here the ss: it says ACTIVE, as you can see there's no opens orders, and my time range is 01:00 - 06:00 SG Time and my local PC time (SG time) is outside those range. {image} I pressed force close all button and restart MT4 and then it said INACTIVE: {image}
You can read the same explanation here: http://www.forexfactory.com/showthre...91#post8631291

Basically, Stop Time Action logic in v1.8 earlier was built by checking the tick's datetime. If tick's datetime is between Stop Time and (Stop Time + 30 seconds), it will execute those logic to close all orders.
But, since the logic is coded that way, there might be some case where your MT4 did not receive any tick in 30 seconds interval from Stop Time, hence the code never been executed.
I have fixed it in v1.9, it will not read the 30 seconds interval anymore. It will execute the logic on the very first tick received after Stop Time. So if your MT4 did not receive any ticks (by any cause like really no ticks received, or maybe your network was down for let's say 30 minutes), the very first tick after Stop Time will execute the logic to close all orders.

{quote} What's the solution? Interested to know. I saw your screenshot where 2 orders with almost same price, slippage? May i know when to turn on EA? And whats the grid interval? Whats the current price interval? Possible to share the set file?
This is a secret which i should keep it.....but since you asked i will give you the answer.

Simply set tp with 20-30pips (depends on ADR), no other settings were changed.


When the market perform a false breakout, tp will be hit at high probability.

If it's a ture BO, your TP will be bypassed and end up with huge profit.

Hi Radityo,
Today I tested with "close all if in profit" in v1.8. The time range is from GMT1900 to GMT2300. But now its already GMT0423 which has passed the stop time. And its profiting right now. The EA still not closing all the orders yet.
and I backtested with v1.8 and v1.9 with same settings and the results are not same. Is it related to the tick issue?

Add on: Bactest v1.8 and v1.9 with "close if no opened" and the results are same.
Thanks!

Yes, this middle point range strategy is just for LIMIT orders, not suitable for STOP orders.

The logic for Stop Time Action is only executed once.

It didn't close maybe due to the tick issue. Or maybe at the point of time the code executing, it was in loss.
Stop Time Action is only executed once during Stop Time within 30 seconds (v1.8) or executed once on the first tick received after Stop Time (v1.9).

Let us say, at the point of executing is not in profit, but later on (in your example: GMT0423) is reaching profit, it will not close the order. At this point of time, the logic will be handled by Close Type "Target Based OR Middle Point".

Judging from the screenshot, it seems not yet reaching the Middle Point logic nor reaching Target Based (see on the dashboard, DyTP: 31.20 USD), while your current profit is only 15.26 USD.

hi radit, im trying to forward test on demo account
using 3 pair * eur/usd gbp/usd usd.jpy

max pending order each side is 20

so for the eur/usd - all 20 buy limit and 20 sell limit - OK
so gbp/usd - only 15 buy limit and 15 sell limit - and the rest is error box ( max pending order )
and for usd/jpy - no order, ( error max pending error )

this kind of error, because of mt4 broker limit ?
or from EA setting ?
i set different magic number

In a simple word, the initial intention for Middle Point was to close all orders that is in profit as quickly as possible before reaching the target, if possible.
Quickly get out of the current cycle in profit as soon as possible and start a new one (if still inside the timerange), rather than keep staying in pending orders waiting the target to be reached.

So, the idea was to close it at the middle point area, where the cycle was initially started.

Why I have to implement this?
LIMIT order is actually a bit scary, but if you can just quickly get out of the market as soon as it gets profit, that'll be great.
STOP order is less scary and seems promising, but in ranging market, that'll be troublesome and hard to get out.

Hi fx,

Would suggest you have your demo accounts with RoboForex as that is one of the more common brokers we are all testing with.
Other brokers might have limitations on the number of orders which can be placed and whatnot. A quick chat with their support should sort you out.

Radityo, one thing i cannot understand, why does the EA behave differently between different demo accounts of the same type and of the same broker? As in, there is a discrepancy in the orders being placed and executed between them inspite of their trading conditions being the same. Any idea?

That is your broker limiting the max pending order.
Seems like you only have max 50 pending orders, am I right?

Even at this point, I can't guarantee 2 different demo accounts with the same settings, same version, same environment will have the exact same result.
There are so many factors.

The code depends on the tick / quote received from the server. I have 5 same accounts in the same broker. Sometimes I noticed that the tick / quote received from one MT4 and another is different, and at some other time one of MT4 is disconnected from the server for a minute.

It could be due to network connection, or the ticks received in a different time in both MT4, it could be due to network package queuing in the broker's server.
Nevertheless, I've tried my best to make the behavior consistent, and it should be consistent since it is only 1 code running.

The best way to test is to backtest it. Try running the same setting, the same date and time range (start - stop), in backtest. Do it like 5 times or more. It should have the exact same result.

so is this BREAK EVEN POINT ?

example, buy limit hit.. and price go up, and before hit the sell limit, the ea will close at middlepoint ( first cycle start )?

No, it's not a break even point. Break even point is where the $0 profit point.

As I said, it depends on your settings. If you are using GTLIMITEURUSD2 or GTL_EU2, once buy limit hit, it will pass through middle point. But it will not close the cycle since the condition is not met, Middle Point Activation (order count) requires 2 open order at least.

So, either it has to go down touching the second buy limit, or go up touching the first sell limit.

Today I even haven't touched the new logic. Planning to finish by end of next week.

Still doing code optimization, since I need it before touching the new logic. Got to restructurize the whole code. Otherwise, the code'll be too messy.
