3. If price moves against the trade by the original SL distance, recovery mode is activated instead of closing the trade.
4. The original TP is removed and the position is managed as a basket.
I reverted that idea. Now, the Grid follows the original closing rules and only add the Grid trading with them.
It allows to us every gentle Gird with 1-2 additions and small dollar Take Profit.

It fixes a bug with SL and TP when Grid is enabled (in currency and points).
You can use SL and TP in points (as in the original expert) and in currency from the Grid settings with Grid or not.
If the Grid is enabled, but you set "Gird maximum total positions" = 1, it uses the Grid's SL and TP in currency without adding to the position.

It is Expert Advisor Plus because I intend to add other features to it, which are only valuable for testing in the MetaTrader's tester.
Like:
- repeating entry signal in case of an error (for example, midnight trade interruption due to swaps calculations)
- averaging of profitable positions (Pyramiding)
- possibly Higher time frame indicators for entry filters.
- ...
Any ideas are welcomed!
Does it work if I upload the EA in EA Studio and then I extract it in MT5 by flag on the grid option ?
> Does it work if I upload the EA in EA Studio and then I extract it in MT5 by flag on the grid option?
Yes, it works.
You can import any strategy and export a Grid export (Expert Advisor Plus)
By default, the Grid is off, and the strategy should work as original.

It fixes Grid Stop Loss in currency.

Dollar Stop Loss and Take Profit works very well in my tests. they are not set to the positions but monitored at every tick. If the strategy makes total floating profit greater than the currency TP or lower than the currency SL, the Expert closes all positions.
If Pair close is enabled, the expert close the last position and only 0.01 lots from the first one on Currency Take Profit.
Great!
Will import my EAs “Ready for Live” which run on incubators, then will export them with the grid active and will benchmark the results with the sourcing EAs into the incubators.
Let’s see !
Thx

I reconsidered the Grid's SL and TP behavior again and reverted it to follow strictly the original strategy.
Now the Grid uses the original entry pips SL and TP for all additional entries. In a result, the new positions are in the limits of the original strategy's protections.
(The previous version of the Grid Expert was using SL and TP calculated according to the average position price).
Trade Safe!
Okay, when can we test it?
Hi Popov,
Here is the my plan to evaluate the Grid version properly.
RfL (Ready for Live) are the EAs that already passed our full workflow filters and are currently production-grade.
PwL (Promotion Watchlist) are close-to-ready EAs still under validation before live promotion.
Test approach:
1. Import all current RfL and PwL into EA Studio (approx 50 EAs in total)
2. Export the Grid version
3. Run controlled backtests and compare PF, DD, win rate, and exposure behavior.
4. Run a 3–6 month parallel forward incubation (Original vs Grid).
5. Compare expectancy, drawdown stability, and exposure consistency.
6. Adopt Grid only if it improves distribution without increasing structural risk.
The objective is not just higher win rate, but better risk distribution with controlled downside.
All data will be progressively published here.
Just let me know when I can start to be effective across time and resources (MT4, demo accounts, VPs).
Thx

This version includes updated algorithm for pair-closing of the Grid positions at currency take profit.
Now, the Grid is able to close the first open position (complete or partial) with one or more of the latest positions if they together make profit equal or higher than the "Grid Take Profit (currency)". This feature shows lower Drawdown on my tests.
> Okay, when can we test it?
It is public now. You can download the "Expert Advisor Plus for MT5" from the Strategy Editor.
> 1. Import all current RfL and PwL into EA Studio (approx 50 EAs in total)
> 2. Export the Grid version
The Expert Advisor Plus works as the ordinary Experts exported from EA Studio by default.
The Grid has to be turned on. The Expert must be tested, and the Grid properties must be adjusted carefully in the MetaTrader's Strategy Tester.
> Just let me know when I can start to be effective across time and resources (MT4, demo accounts, VPs).
I consider this Expert as feature complete now.
I'll write the documentation this weekend.
The Expert Advisor Plus is written in MQL5 and works in MetaTrader 5 only.
MetaTrader 4 is effectively removed from the MetaQuotes' website and the MQL4 documentation is removed also. I cannot maintain MT4 Experts anymore.
Please test the Grid feature carefully and share your experience.
Happy Gridding!
Hello, Traders,
Here is the documentation of Expert Advisor Plus and the Grid functionality.
Have a great weekend!
Hello, Traders,
I uploaded Expert Advisor Plus v1.5
It fixes a bug in the Grid's distance input parameters. It is written that the values are in pips, but actually they were in points. Now I fixed it by correctly convert the pips to points for the markets with 3 and 5 digits.
This fix immediately reduces the Grid's equity drawdown simply because it adds less entries and makes them further apart 
Hello Popov,
I have installed a couple of incubators to test the EA Plus versions derived from existing EA Standard strategies that have already been running in my incubation process for a while. These are already proven profitable EAs, which will continue to run in parallel.
So essentially it’s the same strategies, with and without grid, running on the same broker under parallel benchmarks.
I mentioned several incubators because, honestly, I’ve never seen such a wide range of possible settings for a grid system, and it made me curious :-)
Features like the grid step options and the multiple closing logic make your grid implementation quite unique.
I’ll share all the experiment settings and results here and will post the FxBlue live link soon.
Thanks,
Vincenzo
HI Popov,
in the while i was setting my DOE, I found out something which not clear.
In EA Studio Expert Advisor Plus, if a strategy uses an indicator-based closing signal, how does this behave once the Grid has started?
Specifically:
If the second trade is opened (first grid level) and multiple grid positions are already at market, and then the strategy indicator generates a close signal, does the EA:
1. Close all open grid positions immediately, even if the basket is currently in loss, or
2. Ignore the indicator close signal while the grid is active, and manage the basket only through the Grid mechanisms (Pair Closing, Grid TP/SL in currency)?
In other words, once the grid starts, does the indicator-based exit remain active or is the grid logic exclusively in control of the closing process?
Thx
Vincenzo
Hello Vincenzo,
> In EA Studio Expert Advisor Plus, if a strategy uses an indicator-based closing signal, how does this behave once the Grid has started?
The Strategy applies the closing logic rules in the same way with or without Grid enabled.
> If the second trade is opened (first grid level) and multiple grid positions are already at market, and then the strategy indicator generates a close signal, does the EA:
The indicators' close signal will close all open positions by this expert.
> In other words, once the grid starts, does the indicator-based exit remain active or is the grid logic exclusively in control of the closing process?
The closing indicators logic is active. The Grid may open and close positions on its own, but it is "within" the original strategy's behavior.
Hello Popov,
thank you, this clarification is very helpful.
I would like to confirm one practical implication.
If the original strategy keeps its indicator-based closing logic active even after the Grid has started, then any close signal can close the whole basket, including open grid positions, even if the basket is still in floating loss.
My concern is that almost all strategies generated in EA Studio have at least one exit rule based on indicators.
So, in practical terms:
- Does this mean that Expert Advisor Plus is mainly suitable for strategies without dynamic indicator-based closing rules?
- Or is there a recommended way to use the Grid effectively when the original strategy includes indicator exits?
In other words, if the original exit logic remains fully active, it seems that the Grid recovery logic may often be interrupted before it can do its job. I would like to understand whether this is the intended design and how you recommend handling it in practice.
Best regards,
Vincenzo
> If the original strategy keeps its indicator-based closing logic active even after the Grid has started, then any close signal can close the whole basket, including open grid positions, even if the basket is still in floating loss.
The strategy's trading logic does not change when the Grid is enabled.
Think of the Grid (Averaging Down) as a new opportunity to add lots in the same direction as the initial position at a more favourable price. Another viewpoint is that the Grid can be considered as a money-management system.
This Grid implementation, "Averaging Down," is not an independent trading system.
It opens a position only after the strategy makes its original entry.
The Grid stops acting when the strategy raises a close signal, which will effectively close all open positions (the original one and any additional averaging-down entries), or if the market reaches any of the strategy's protections, such as SL, Trailing SL, or TP.
>- Does this mean that Expert Advisor Plus is mainly suitable for strategies without dynamic indicator-based closing rules?
I cannot confirm that. It depends on the particular strategy.
It would be great if we had a backer with Grid in EA Studio, but this is not the case currently.
> In other words, if the original exit logic remains fully active, it seems that the Grid recovery logic may often be interrupted before it can do its job.
Yes, it is true. The Grid, however, does not aim to make a bad strategy profitable.
What are my observations:
- The Grid entries increase the traded volume and the Margin requirements. For that reason, I advise a minimal initial entry of 0.01 lots.
- The Grid works better (or at least reveals its potential) when the strategy has a wider Stop Loss range.
- There is a possibility to create a strategy specially designed to utilise the Grid capabilities. It particularly means the exit rule is "Do not Exit" or one that limits upward market movement.
- The "Grid Take Profit (currency)" option works well even with the strategy's original entry.
- A strategy with Grid embedded has a higher chance of showing a short-term profit and numerous consecutive winning trades.
- Trading multiple Grid strategies is much riskier than strategies with fixed entry lots.
- A single Grid strategy on a larger account may work well if we can afford a large drawdown.
- A fixed-lot strategy is much safer on a smaller account.
Thanks Popov, as usual great willingness and transparency.
This is what I am going to do then:
Executive Summary
I am running a DOE to test whether an EA Studio Expert Advisor Plus Grid overlay can improve the behavior of already good strategies, rather than trying to rescue weak ones.
The starting point is a pool of profitable incubation EAs across symbols such as
AUDCAD, AUDUSD, NZDCAD, EURCAD, EURGBP, EURJPY, GBPJPY, GBPUSD, XAUUSD, and XAGUSD.
The idea is simple:
most of these strategies already work well, but a minority of trades fail to reach TP and move into adverse territory.
The question is whether a controlled Grid overlay can improve the management of these losing cases and potentially enhance not only classic KPIs, but also strategy longevity and robustness.
A key clarification from Popov is that the Grid is not an independent trading system. It works within the original strategy logic. This means that if the strategy has indicator-based exits, SL, trailing SL, or TP, those remain active and can close the whole basket even after Grid entries have started.
Because of this, the experiment focuses on testing Grid as an overlay recovery layer, not as a standalone Grid strategy.
The DOE structure is therefore:
* Original strategy as control
* Bucket 01 = Fibonacci Grid
* Bucket 02 = Custom Grid A
* Bucket 03 = Custom Grid B
Each selected EA is installed in 3 additional variants, while the original remains unchanged in incubation.
To track the test arms cleanly, each bucket gets a numeric suffix added to the original magic number:
* 01 = Fibonacci
* 02 = Custom A
* 03 = Custom B
Example:
`1740201819` → original
`174020181901` → Fibonacci
`174020181902` → Custom A
`174020181903` → Custom B
The broader objective is not to “gomove to a full grid system trading,” but to verify whether a carefully designed Grid variance on top of a strong base strategy can improve the handling of adverse trades without destroying the original edge.
Willing to share here to anyone interested the full dataset.
Thanks Popov, and trade safe to everyone.
Vincenzo
Hi Vicenzo,
I forgot to mention that the Grid system works well in the MetaTrader's Strategy Tester.
My advice is to test the strategies first in MetaTrader with "Every tick based on real ticks".
I have three reasons for that:
- test the strategy behaviour on real historical spread (I mean "really" real instead of bar-data-rounded real). It catches spread rounding issues after a weekend gap.
- Testing the performance of the Grid and parameters adjustments.
- Catch a potential bug in the Expert's trading logic. (less probably, but always possible)
Happy trading!
Hi Popov,
1 question: After a partial Pair Closing, if one or more positions remain open from the grid, can the original strategy open a new base entry before the whole basket is fully closed, or does it wait until all positions of that expert are flat?
is it possible to have the sequential trade's numbers into the comment ?
> After a partial Pair Closing, if one or more positions remain open from the grid, can the original strategy open a new base entry before the whole basket is fully closed
No, it cannot. The strategy opens its "original" position only if there are no open trades for this symbol, period, and magic number.
> Is it possible to have the sequential trade's numbers in the comment?
It will become a mess when the Grid performs several pair closings.
thx
