🎯 Objective

Fix two issues preventing SimpleORBNT8 from appearing in NT8 strategy dropdown:

1. NT8StrategyBase (abstract) incorrectly appears in dropdown
2. SimpleORBNT8 has runtime error preventing it from loading

---

🔧 Fix 1: NT8StrategyBase.cs - Remove Name from abstract class

File

src/NT8.Adapters/Strategies/NT8StrategyBase.cs

Problem

Abstract base class sets Name = "NT8 SDK Strategy Base" which makes it appear in the strategy dropdown. Abstract strategies should NOT have a Name.

Change: Remove or comment out Name assignment

Find (around line 97):

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description = "SDK-integrated strategy base";
                Name = "NT8 SDK Strategy Base";
                Calculate = Calculate.OnBarClose;

Replace with:

        protected override void OnStateChange()
        {
            if (State == State.SetDefaults)
            {
                Description = "SDK-integrated strategy base";
                // Name intentionally not set - this is an abstract base class
                Calculate = Calculate.OnBarClose;

🔧 Fix 2: SimpleORBNT8.cs - Guard Instrument null access

File

src/NT8.Adapters/Strategies/SimpleORBNT8.cs

Problem

ConfigureStrategyParameters() accesses Instrument.MasterInstrument which is null when NT8 loads the strategy for the dropdown list, causing a runtime exception that removes it from available strategies.

Change: Add null guard

Find:

        protected override void ConfigureStrategyParameters()
        {
            _strategyConfig.RiskSettings.DailyLossLimit = DailyLossLimit;
            _strategyConfig.RiskSettings.MaxTradeRisk = MaxTradeRisk;
            _strategyConfig.RiskSettings.MaxOpenPositions = MaxOpenPositions;

            var pointValue = Instrument.MasterInstrument.PointValue;
            var tickSize = Instrument.MasterInstrument.TickSize;
            var dollarRisk = StopTicks * tickSize * pointValue;

            if (dollarRisk > _strategyConfig.RiskSettings.MaxTradeRisk)
                _strategyConfig.RiskSettings.MaxTradeRisk = dollarRisk;

            _strategyConfig.SizingSettings.RiskPerTrade = RiskPerTrade;

Replace with:

        protected override void ConfigureStrategyParameters()
        {
            _strategyConfig.RiskSettings.DailyLossLimit = DailyLossLimit;
            _strategyConfig.RiskSettings.MaxTradeRisk = MaxTradeRisk;
            _strategyConfig.RiskSettings.MaxOpenPositions = MaxOpenPositions;

            // Guard: Instrument is null during strategy list loading
            if (Instrument != null && Instrument.MasterInstrument != null)
            {
                var pointValue = Instrument.MasterInstrument.PointValue;
                var tickSize = Instrument.MasterInstrument.TickSize;
                var dollarRisk = StopTicks * tickSize * pointValue;

                if (dollarRisk > _strategyConfig.RiskSettings.MaxTradeRisk)
                    _strategyConfig.RiskSettings.MaxTradeRisk = dollarRisk;
            }

            _strategyConfig.SizingSettings.RiskPerTrade = RiskPerTrade;

✅ Verification

# Build must succeed
dotnet build src\NT8.Adapters\NT8.Adapters.csproj --configuration Release

# Redeploy
.\deployment\Deploy-To-NT8.ps1

In NT8 after recompile:

• "NT8 SDK Strategy Base" NO LONGER appears in dropdown
• "Simple ORB NT8" DOES appear in dropdown
• "Minimal Test" still appears (if compiled)

---

🚨 Constraints

• Two surgical edits only
• C# 5.0 syntax
• Do NOT change other logic
• All tests must pass

---

📋 Git Commit

git add src/NT8.Adapters/Strategies/NT8StrategyBase.cs
git add src/NT8.Adapters/Strategies/SimpleORBNT8.cs
git commit -m "fix: Make abstract base invisible, guard Instrument access

- Remove Name from NT8StrategyBase (abstract shouldn't appear in dropdown)
- Add null guard for Instrument access in ConfigureStrategyParameters
- Prevents runtime error when NT8 loads strategy list

Fixes: SimpleORBNT8 now appears in strategy dropdown"
