undefined properties & setup idx increments

[zapphyre]

I have two insides for you:

in your countdown methods you are referring to item's TDSTBuy/TDSTSell propertis, but item here is the ohlc bar so you have them undefined.

you may notice, your setup indexes are all zeros up to nine iteration. (that's from your test). This is because you have implemented conditions needed to turn true quite complex. I refer to these lines:

      let closeLessThanCloseOf4BarsEarlier = ohlc[i].close < ohlc[i - 4].close;
...
      resultObj.bearishFlip = ohlc[i - 1].close > ohlc[i - 5].close && closeLessThanCloseOf4BarsEarlier;
...
      if (resultObj.bearishFlip || (result[i - 1].buySetupIndex > 0 && closeLessThanCloseOf4BarsEarlier)) 
        resultObj.buySetupIndex = (result[i - 1].buySetupIndex + 1 - 1) % 9 + 1;

as I understand TDSequential you don't need that complex conditions. if you would have setup increments based on the closeLessThanCloseOf4BarsEarlier conditions, you will have setup numbers after first four candles.
So can you give me your reasoning for this implementation?
