Here is my attempt to develop a simple grid.

It is not based on any indicator, just on math.

I used only first 8 months of 2020 (01.01.2020-01.09.2020) for optimization, but it survives even in hard 2018!

The Start lot is set to 0.1 (not 0.01!) and it has special sense — martingale coefficient 1.1 is used, and 0.01 can't be enlarged properly!

So, you probably need cent-account for safe trading with this grid.

I've launched 2 cent-accounts for test (with €100 deposit on each): 

• Weltrade: https://www.mql5.com/en/signals/877054
• and Roboforex: https://www.mql5.com/en/signals/877024

UPD:

• 06.12 account at FBS was launched by Sai,
• 14.12 Robo was stopped because of worse performance,
• 17.12 one more account at FBS was launched by me: https://www.mql5.com/en/signals/892276
• 24.12 my FBS account has been stopped. It performs like Weltrade, no need to have 2 accounts for the same set.
• 27.01.2022 Weltrade account has been stopped out

To open the same accounts, please, use my referral links:

• Weltrade (partner id 33030)
• Roboforex (partner id httm)
• FBS (partner id 18166868)

The max draw-down within last 2 years was about 25`000 ($250), so I'm ready to deposit another €150 on each account if strong trend occurs.

In 2018 DD reached 40`000 ($400). And I'm not sure I ready to something like this with real money.

However, the strategy produces around 15-20K ($150-200) every 6 months. So, it has sense to use it even if it sometimes blows the account =)

Here is the result with IC-Markets from 01.01.2018 to 01.12.2020:

For the same period on Weltrade:

And the same test for Roboforex:

I made stress-tests using execution delays, and it passed them successfully (tried up to 150 ms delay).

Set files for version 2.21:

CP_MT5_EURUSD_Grid8.set

CP_MT4_EURUSD_Grid8.set

Set files for version 2.36 (uploaded 18.08.2021):

CP_MT5_EURUSD_Grid8_2.36.set

CP_MT4_EURUSD_Grid8_2.36.set

Please, convert "Min profit to close" for the "Partial close" to your account currency! It was optimized for USD account.

On EUR account I use value 4.5 instead of 5.0 (4.5 EUR is approximately equals to 5 USD).

My goal is to make such set for several currency pairs (or other instruments), so drawdown remain the same, but profit is multiplied.
