Another update, I tried it with the Machine Learning snippet of @juanj and leaving most of the settings at default produced slightly better results than using the latest optimized value of Period2 = 9.

The code that was inserted:

// Heuristics Algorithm Start

If onmarket[1] = 1 and onmarket = 0 Then
optimize = optimize + 1
EnDif

StartingValue = 9
ResetPeriod = 1 //Specify no of months after which to reset optimization
Increment = 1
MaxIncrement = 4 //Limit of no of increments either up or down
Reps = 6 //Number of trades to use for analysis
MaxValue = 100 //Maximum allowed value
MinValue = 1 //Minimum allowed value

once monthinit = month
once yearinit = year
If (year = yearinit and month = (monthinit + ResetPeriod)) or (year = (yearinit + 1) and ((12 - monthinit) + month = ResetPeriod)) Then
ValueX = StartingValue
WinCountB = 0
StratAvgB = 0
BestA = 0
BestB = 0
monthinit = month
yearinit = year
EndIf
once ValueX = StartingValue
once PIncPos = 1 //Positive Increment Position
once NIncPos = 1 //Neative Increment Position
once Optimize = 0 ////Initialize Heuristicks Engine Counter (Must be Incremented at Position Start or Exit)
once Mode = 1 //Switches between negative and positive increments
//once WinCountB = 3 //Initialize Best Win Count
//GRAPH WinCountB coloured (0,0,0) AS "WinCountB"
//once StratAvgB = 4353 //Initialize Best Avg Strategy Profit
//GRAPH StratAvgB coloured (0,0,0) AS "StratAvgB"

If Optimize = Reps Then
WinCountA = 0 //Initialize current Win Count
StratAvgA = 0 //Initialize current Avg Strategy Profit

For i = 1 to Reps Do
If positionperf(i) > 0 Then
WinCountA = WinCountA + 1 //Increment Current WinCount
EndIf
StratAvgA = StratAvgA + (((PositionPerf(i)*countofposition[i]*100000)*-1)*-1)
Next
StratAvgA = StratAvgA/Reps //Calculate Current Avg Strategy Profit
//Graph (PositionPerf(1)*countofposition[1]*100000)*-1 as "PosPerf1"
//Graph (PositionPerf(2)*countofposition[2]*100000)*-1 as "PosPerf2"
//Graph StratAvgA*-1 as "StratAvgA"
//once BestA = 300
//GRAPH BestA coloured (0,0,0) AS "BestA"
If StratAvgA >= StratAvgB Then
StratAvgB = StratAvgA //Update Best Strategy Profit
BestA = ValueX
EndIf
//once BestB = 300
//GRAPH BestB coloured (0,0,0) AS "BestB"
If WinCountA >= WinCountB Then
WinCountB = WinCountA  //Update Best Win Count
BestB = ValueX
EndIf

If WinCountA > WinCountB and StratAvgA > StratAvgB Then
Mode = 0
ElsIf WinCountA < WinCountB and StratAvgA < StratAvgB and Mode = 1 Then
ValueX = ValueX - (Increment*NIncPos)
NIncPos = NIncPos + 1
Mode = 2
ElsIf WinCountA >= WinCountB or StratAvgA >= StratAvgB and Mode = 1 Then
ValueX = ValueX + (Increment*PIncPos)
PIncPos = PIncPos + 1
Mode = 1
ElsIf WinCountA < WinCountB and StratAvgA < StratAvgB and Mode = 2 Then
ValueX = ValueX + (Increment*PIncPos)
PIncPos = PIncPos + 1
Mode = 1
ElsIf WinCountA >= WinCountB or StratAvgA >= StratAvgB and Mode = 2 Then
ValueX = ValueX - (Increment*NIncPos)
NIncPos = NIncPos + 1
Mode = 2
EndIf

If NIncPos > MaxIncrement or PIncPos > MaxIncrement Then
If BestA = BestB Then
ValueX = BestA
Else
If reps >= 10 Then
WeightedScore = 10
Else
WeightedScore = round((reps/100)*100)
EndIf
ValueX = round(((BestA*(20-WeightedScore)) + (BestB*WeightedScore))/20) //Lower Reps = Less weight assigned to Win%
EndIf
NIncPos = 1
PIncPos = 1
ElsIf ValueX > MaxValue Then
ValueX = MaxValue
ElsIf ValueX < MinValue Then
ValueX = MinValue
EndIF

Optimize = 0
EndIf
graph valuex
// Heuristics Algorithm End


p2 = valueX

Period2 is later set to p2, as this is the variable to be optimized.

See attachments for the difference in result over the last days. Unfortunately I only have access to 200k backtesting bars though.

@juanj Fantastic work with the Machine Learning!
