Pairs || No restrictions. All pairs available.
- It can be used not only for FX pairs such as “EURUSD” and “USDJPY”, but also for “S&P500 (CFD)”, “XAUUSD (futures)”, “BTCUSD (cryptocurrency)”, etc.

Determining the grid range

In this EA, a trading strategy is made based on the highest price (Highest) and lowest price (Lowest) of the past [PricePeriod] months from the current candlestick.

The calculation formula for each item is as follows.

Highest = highest price in the last [PricePeriod] months
Lowest = lowest price in the last [PricePeriod] months
CenterLine = Distance / 2 + Lowest
Distance = Highest - Lowest CenterLine = Distance / 2 + Lowest

These values are used to calculate the “interval” for making trades.

About trading

All trades are made with market orders. No limit orders
- As a result, it is now possible to suppress trades when Spread is expanded

Trading methods are roughly divided into inside and outside the core range
- Within the core range, both short and long trades are made
- Only short trades above the core range
- Only long trades under the core range

The upper limit of the core range is coreHighest, and the lower limit is coreLowest.

CoreHighest = CenterLine + Distance * [coreRange]
CoreLowest = CenterLine - Distance * [coreRange]

core range: from CoreLowest to CoreHighest

TakeProfit and trade “interval” for each position

There is one positionin in the same direction for each “interval”.

The calculation formula of “interval” is as follows.

in the core range

interval = Distance * ( 2 * [coreRange] ) / [positionCore]

But if interval < [minTP]pips then interval = [minTP] 
But if interval > [maxTP]pips then interval = [maxTP]

outside the core range

interval = Distance * ( 1- 2 *[coreRange] ) / [positionHalf]

But if interval < [minTP]pips then interval = [minTP] 
But if interval > [maxTP]pips then interval = [maxTP]

In other words, if you already have a position within the upper or lower interval from the current price, the trade will not take place.

Also, the take profit value of the position (TakeProfit) is the same value as the interval.

Basically, the maximum number of positions will be close to [positionHalf]+[positionCore], but not if the interval is less than [minTP]pips or more than [maxTP]pips.

Stop loss

※[sl] parameter is available only in pro edition

By default, no stop loss is provided because the basic strategy of thie EA is not to set a stop loss.

In pro version, you can set stoploss by pips.

The value of stopplos will be,

Stoploss(Long trade) = Ask - [sl]pips
Stoploss(Short trade) = Bid - [sl]pips

※ No stop loss is provided if you set [sl] = 0(Default setting)

About the number of lots

※[risk] parameter is available only in pro edition

Two methods are available: fixed lot method and variable lot method.

If the number of lots is less than the minimum lot specified by the broker, the trade will not take place.

Fixed lot method

In the fixed lot method, lot is determined by the following formula.

lot = [lot]

Variable lot method

In the variable lot method, lot is determined by the following formula.

lot = free margin * [risk] / margin required to buy 1 lot of trading pair

When the drawdown becomes large, it is possible to reduce the lot number and increase the lot number when there is room to do compound interest trading with reduced risk.
Easy to balance when trading multiple pairs.
- For example, when trading 1 lot, the required margin is different between EURUSD and USDJPY, so with the fixed lot method, the bet will be biased towards one of the pairs.
- In the floating lot method, this problem does not occur because the lot is determined based on the excess margin.

※When using variable lots, the number of lots is calculated based on free margin, so the higher the leverage, the more free margin and the higher the risk than expected. Be careful when changing leverage.

※When using variable lots, set [lot] to 0.

safe function

※[spreadLimit][stopEquity][stopMarginLevel][stopDrawDownPer] parameters are available onlyin pro edition

Pause trading if the current spread is greater than or equal to [spreadLimit]
- To disable, set [spreadLimit] = 99999999…
Pause trading when current equity is less than [stopEquity]
- To disable, set [stopEquity] = 0
Pause trading when the margin level falls below [stopMarginLevel]
- To disable, set [stopMarginLevel] = 0
Pause trading when drawdown exceeds [stopDrawDownPer]
- To disable, set [stopDrawDownPer] = 100

magicNumber

To identify the position managed by this EA, set [magicNumber] so that it does not overlap with other EAs.

This EA operates only on the positions associated with [magicNumber].

Log

Troubles that occur on the EA are displayed on the upper left of the chart.

If you turn on [debugMode], you can check the log not only on the upper left of the chart but also on MT5 Journal

※When debugMode is ON, if too many logs accumulate, MT5 and machine storage may be squeezed and malfunction may occur. Please pay attention to the remaining storage capacity when using.

About optimization

Higher performance can be achieved by optimizing the pair you want to use.

When managing multiple pairs, risk diversification can be expected by choosing pairs with less correlation.
Specify the minimum lot (0.1 or 0.01) for [lot].
Set [coreRange] < 0.5.
In pro version,
- Set [risk] = 0
- It is recommend to disable safe functions
It is recommended to use “Complex Criterion Max” for optimization evaluation
For optimization, I recommend a testing period of at least 3 years.
To avoid curve fitting, it is recommended to dedicate half of the testing period to forward testing.

The recommended optimization items are as follows.

Please adjust while consulting with your preferences and machine specs.
