It's a risky. It's easy to use. It's martingale.
(M) EA Operation mode
(0) Init order size (if Auto)
=== Strategy One
(1) Grid size (pips)
(2) Martingale multiplier
(3) Max martingale levels
(4) Target profit ($)
(5) Suspend: loss over ($)
(6) Close all: loss over ($)
(7) Magic number 1
(8) Magic number 2
(9) Magic number for manual order
In Auto_Initial_Orders mode (M), EA places one buy and one sell order when started. In Manual_Initial_Orders mode (M), it starts in "Waiting..." mode and waits for open orders. If there are open orders, EA will enter "Running" mode.
If account running loss is over (5), it goes to "Suspended" mode, the EA will be suspended - no new orders will be opended and no opened orders will be closed. When the account running loss below (5) again, the EA will be reactivated. Anytime, regardless of the EA mode, if account running loss is over (6), all opened orders will be closed, and going back to "Waiting..." mode.
In addition, to help understand the recent market situation, it shows on the chart the figures of 2-hour, 4-hour and 6-hour pip-ranges of the last few days. Also, there are horizontal lines showing the high/low of yesterday, the last 5-days, 10-days, 20-days, 50-days and 100-days.
(a) The EA counts all the orders of the current instrument with magic number (7), (8) and (9). And (9) is the magic of the orders that are created manually, usually it's 0.
(b) This EA could be risky if not used properly. It should be more suitable in ranging market with appropriate parameters, specifically (0), (1), (2) and (3). It's highly recommended to test on demo account to find the right parameters for your instrument, your account and your acceptble risk level. And, it's not suggested to leave it unattended.
(c) I usually used it with my utility EasyMonitor (https://www.mql5.com/en/market/product/68139) that plots the running P/L. From its graph, we can have an idea of the risk.
Nothing is guarantee, use it with care and take your own risk. Good luck.
