Determination of grid range

This EA will create a trading strategy based on the Highest and Lowest prices during the past [PricePeriod] months from the current candlestick.

The formulas for each item are as follows

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

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

About Trade

• All trades are executed by market orders. No limit orders are placed.
  • This allows us to control trades during Spread expansion.

• Grid trade, so no stop loss is set

• Trades are broadly divided into two main categories: those inside the core range and those outside the core range.
  • Within the core range, both short and long trades take place.
  • Above the core range, only short trades are made.
  • Below the core range, only long trades are made.

The upper and lower limits of core range are coreHighest and coreLowest, respectively.

CoreHighest = CenterLine + Distance * [coreRange] CoreLowest = CenterLine - Distance * [coreRange] core range: CoreLowest ~ CoreHighest

TP and trade interval for each position

There is one position in the same direction for each interval.

The formula for calculating the interval is as follows

• If in core range

interval =istance * ( 2 * [coreRange] ) / [positionCore] However, if interval < [minTP]pips, then interval = [minTP] However, if interval > [maxTP]pips, interval = [maxTP] if interval > [maxTP] pips.

• Outside core range

interval = Distance * ( 1- 2 *[coreRange] ) / [positionHalf] If, however, interval < [minTP]pips, then interval = [minTP] If, however, interval > [maxTP]pips, However, if interval > [maxTP] pips, then interval = [maxTP].

In other words, if you already have a position within the upper or lower INTERVAL range from the current price, no trade will be made.

The take-profit value of a position (TakeProfit) is also the same value as interval.

Basically, the value is close to [positionHalf] + [positionCore] with respect to the maximum number of positions, unless the interval is less than [minTP]pips or more than [maxTP]pips.

stop-loss

By default, no stop loss is provided. This is because the basic strategy of this EA is to not take a stop loss.

The specific values of the stop loss are as follows

Stoploss (long trade) = Ask - [sl]pips Stoploss (short trade) = Bid - [sl]pips * When [sl] = 0, no stop loss is set (default setting)

About the number of lots

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

If the number of lots is less than the minimum lot size specified by the broker, no trade will be made.

fixed lot method

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

lot = [lot].

variable lot method

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

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

• When drawdowns are large, the number of lots can be lowered, and when there is room, the number of lots can be raised, allowing for risk-free compound interest trading.
• It is easy to balance when trading multiple pairs.
  • For example, when trading one lot, the margin requirement differs between EURUSD and USDJPY, so the fixed lot method will result in a bias toward one of the pairs.
  • With the variable lot method, this problem does not occur because the lot is determined based on the surplus margin.

In the case of variable lot, the number of lots is calculated based on the surplus margin, so the higher the leverage, the more the surplus margin increases and the higher the risk becomes. Please be careful when changing leverage.

If you want to use a variable lot, set [lot] to 0.

safe function

• If the current spread is greater than or equal to [spreadLimit], the trade will be paused
  • To disable, set [spreadLimit] = 99999999...
• Transactions will be paused if current valuation is less than [stopEquity
  • To disable, set [stopEquity] = 0
• Suspend trading when margin maintenance falls below [stopMarginLevel].
  • To disable, set [stopMarginLevel] = 0
• Transactions are paused when drawdown exceeds [stopDrawDownPer].
  • To disable, set [stopDrawDownPer] = 100

magicNumber

To identify the positions managed by this EA, set [magicNumber] to a value that does not cover any other EA.

This EA will only operate on positions tied to [magicNumber].

log

Any problems that occur on the EA will be displayed in the upper left corner of the chart.

When [debugMode] is turned on, you can check the log not only on the top left of the chart, but also on the Journal of MT5.

*When debugMode is turned on, too many logs accumulated may overwhelm the storage space of MT5 and the machine, causing malfunctions. Please pay attention to the amount of remaining storage when using this function.

About Optimization

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

• When managing multiple pairs, risk diversification can be expected by selecting pairs with low correlation.
• [lot] should be the minimum lot (0.1 or 0.01).
• [coreRange] < 0.5. If
• Set [risk] = 0
• It is recommended to turn off the SAFE function
• We recommend using "Complex Criterion Max" for optimization evaluation.
• For optimization, we recommend a testing period of at least three years.
• To avoid curve fitting, it is recommended that half of the testing period be devoted to forward testing.

Recommended optimization items are as follows

Please make adjustments based on your own preferences and machine specs.

Variable	Start	Step	Stop.
pricePeriod	1	1	96
coreRange	0	0.05	0.5
positionHalf	1	1	50
positionCore	1	1	50

Error messages encountered during optimization

If the following error occurs during optimization, optimization may not be working.

In this case, it is recommended to check the details of the error with "Visualize Test".

Enter the set of parameters that may have failed and start the "Visualize Test

Error details (alert messages) can be checked.
