Understanding Portfiolo and trade management of single and multiple strategies

I have seen some interest in combining multiple trading strategies in this forum and questions about how or if that approach helps reduce risk and improve returns. In this thread we will discuss these issues and apply real examples of how to use this approach.
 
Do you want to combine multiple intra-day trades or multiple position/swing trades or some combination of both?

Position management is going to be difficult if you are overlaying multiple strategies in the same account as you will need to look at trades as buying/selling to open/close (almost like options).

You may as well just have an index fund if you're going to do "that". :(

What do you think this approach produces low returns? If that is what your thinking your totally wrong. Combining multiple systems does not decrease returns only drawdowns if you pick uncorrelated systems. I have developed many different portfiolo of systems and markets which have MAR ratio's and Sharpe ratio's better than 1.
 
It's an approach that works for me. Interesting that this is under trade management because that is clearly my weak point. Rather then try to manage the individual trades I keep the entry and exit criteria very simple so I can take a lot of trades at once, across multiple strategies. It makes my portfolio more scalable and less susceptible to some adverse event in any particular trade. Because I trade stocks long and short I don't worry too much about what the market does.
 
Let's now discuss the concept of trading a larger portfiolo and limited the number of trades which can be open at one time to a given number. TradersStudio has two major concepts, session and tradeplans. Sessions are one system run on one or more markets. Tradeplans are a meta control of session, sessions run one bar at a time and then control is passed to the tradeplan. It has access to all the market and session objects. It can modify orders and place new orders.


You can see below an example tradeplan which trades a large stock portfiolo and limits open positions. It is also limited to a 1 position per day.

End If

SessCount = TradePlan.SessionCount

For Index = 0 To SessCount - 1
DollarsPerTrade = TradePlan.SummEquity / MaxPositions
TradePlan.Session(Index).UnitSize = 1

CustPer = MyCustomPerformanceEx(Index)


TradePlan.Session(Index).SetCustomPerformanceEx(CustPer)
TradePlan.Session(Index).RankingType= Ordinal

' For each session Loop though the trading plans.
For M = 0 To TradePlan.Session(Index).MarketCount - 1
Rating = TradePlan.Session(Index).GetCustomPerformanceRankEx(TradePlan.Session(Index).Market(M).Symbol(0))

Dim iGlobalCount,iActiveOrderCount
TradePlan.Session(Index).SuperCustomRank(TradePlan.Session(Index).Market(M).Symbol(0),iGlobalCount,iActiveOrderCount)
If tradeplan.OpenTradeCount <MaxPositions Then

If iActiveOrderCount=1 And iGlobalCount<MaxPositions Then
TradePlan.Session(Index).Market(M).EntryNumUnits = Floor((DollarsPerTrade) / TradePlan.Session(Index).Market(M).Data(0, "TSCLose", 0))
Else
TradePlan.Session(Index).Market(M).EntryNumUnits = 0
End If
End If
TradePlan.Session(Index).Market(M).ExitNumUnits = TradePlan.Session(Index).Market(M).NumContractsHeld
Next
Next
End Sub

Here is a custom ranking function it used in the code above. It's also used so we only rank markets with a active entry.

Function MyCustomPerformanceEx(Index As Integer) As Array
Dim MCount As Integer
Dim CustomPer As Array
Dim count As Integer

MCount = TradePlan.Session(Index).MarketCount

ReDim(CustomPer, MCount, 3)

For count = 0 To MCount - 1
' If TradePlan.Session(Index).Market(count).HasActiveOrder = True Then
CustomPer[count, 0] = TradePlan.Session(Index).Market(count).Symbol(0)
CustomPer[count, 1] = TradePlan.Session(Index).Market(count).Data(0, "TSCLose", 0)/TradePlan.Session(Index).Market(count).data(0, "TSCLose", 40)
CustomPer[count, 2] =TradePlan.Session(Index).Market(count).IsActiveOrders(False)

'EndIf
Next

MyCustomPerformanceEx = CustomPer
End Function
