IsEmaBullishCross Or IsEmaBearishCross Always false

Hello I am trying to figure out how to know if the Ema is Bullish or Bearish.

I did a backtesting using IsEmaBullishCross and IsEmaBearishCross and they are working fine

` var buyRule = Rule.Create(ic => ic.IsEmaBullishCross(21, 55)); var sellRule = Rule.Create(ic => ic.IsEmaBearishCross(21, 55));

        var runner = new Trady.Analysis.Backtest.Builder()
            .Add(candles)
            .Buy(buyRule)
            .Sell(sellRule)`

The problem is when I am trying to get the buy signal and sell signal from the exchange always is False.

I am using the IndexedCandle like this:

` var ic = new IndexedCandle(candles, candles.Count - 1); var buyRule =(ic => ic.IsEmaBullishCross(21, 55)); var sellRule = (ic => ic.IsEmaBearishCross(21, 55));

`

Maybe I am doing something wrong.

I would appreciate some help.

I did my own testing and I found something very interesting I implemented my own indicator called TemaIndicator I followed the examples and I did thisd

//public static bool IsTemaBullishCross(this IIndexedOhlcv ic, int periodCount1, int periodCount2) // => ic.Get<ExponentialMovingAverageOscillator>(periodCount1, periodCount2).ComputeNeighbour(ic.Index) // .IsTrue((prev, current, _) => prev.Tick.IsNegative() && current.Tick.IsPositive());

    //public static bool IsTemaBearishCross(this IIndexedOhlcv ic, int periodCount1, int periodCount2)
    //    => ic.Get<TemaIndicatorOcillator>(periodCount1, periodCount2).ComputeNeighbour(ic.Index)
    //         .IsTrue((prev, current, _) => prev.Tick.IsPositive() && current.Tick.IsNegative());

Same as many extensions when I use them with back testing is working fine but with real data never always they return false like macd crossing, emabearishcross, emabullishcross etc…

I modified this extension like this:

public static bool IsTemaBullishCross(this IIndexedOhlcv ic, int periodCount1, int periodCount2)
    {

// original code var test = ic.Get<ExponentialMovingAverageOscillator>(periodCount1, periodCount2).ComputeNeighbour(ic.Index) .IsTrue((prev, current, _) => prev.Tick.IsNegative() && current.Tick.IsPositive());

// traditional way var tema1 = ic.Get<TemaIndicator>(periodCount1).Compute()[ic.Index]; var tema2 = ic.Get<TemaIndicator>(periodCount2).Compute()[ic.Index]; if (tema1.Tick.Value > tema2.Tick.Value) { return true; } else { return false; }

    }

and finally the cross was fired …

there is a bug with the extensions.

I would like to help to fix the problem but for now is the only way I found to fix them.

Thank you!
