I have not had a chance to look at the code or backtest the
Blackdog strategy, but I have been watching it on the NQ 2min the
last day and a half. I have noticed that the "long" and
"short" bubbles as well as some of the arrows "repaint" -
they could be there and then when the next bar completes, they
could be gone - or even two bars later. This makes the
strategy look better than it might be in "real time" . Having
said that, it has helped me be ready for a potential direction
The thing you have to understand about these wave systems is
that they all do this repainting, Matt and I have looked at a
number of them over the years.
They will remove the highs or the lows as more data gets added
so they look better historically than they do in real time. They
tend to work pretty well in trending markets, and to not work that
well in chop. They're a useful trading tool but very hard to use
for a programatic system.
The best use case is probably identifying intraday inflection
points, but you might not be able to tell that it was a good
inflection point until an hour or two later.
As an aside the admins over at use think script felt the need to
post a similar warning in the thread brophy linked because they do
look so seductive at first glance, as always there's no grail, just
things that might help with your trading style and give you a
little bit of an edge.
thanks for posting that James, it's a great point, I had just
opened it and have been looking at it a bit.
1. The repainting of past trades/bars is an issue for a
strategy. When you look at past trades they look great but they
might not have done that in reality and will change and disappear -
it looks far better in the past than it was in practice. We've
looked at strategies like this before and at the time came to the
conclusion that we couldn't run them - I ran money with some of
them and the results were very frustrating because of that. If you
go to the forum on the TS side where that strategy is posted the
Admin has a post about waring about this.
2. remember that the market has been having big intra day swings
for the past 3 weeks and even MA cross strategies would work well
in that. Where you would have issues is more of a sideways chop
day. Also, on that forum one guy comments that he's been using a 5
and 15 EMA cross strategy and found it better because the signals
were real, and you know how I don't like MA cross strats.
here's a link to the forum where you can read posts about it
again I still have to investigate it more fully but for now it
looks more like a nice tool to use but not some grail strategy -
it's more of an indicator/tool
I'd like to thank Brophy for posting it, I really appreciate
when folks share info that might help us all
I was planning to port over to Tradestation and Trading View,
however gonna put that on hold because it's not a strategy that can
be automated as I discussed above. It's really more of an
indicator, and realize it will not look as good in real time as the
painted past. We have a lot on our plate and James made some
progress on it, however it's something we'll come back to at a
later date and finish it and post it for those other platforms. In
the meantime you can monitor it for free on TOS through its paper
trading - but it will be delayed data unless you open an
Thanks, Matt. True. As a suggestion, I use longer-term charts
which do not have the habit of "repainting" so much - like trading
in the daytime period. Thanks to you and Steve for all your hard
Good point James. I have added an SLO STO 10,3 for that very
Agreed.. definitely helps. Would like to use it for longer time
frames and may get less "repaint" but its already been super
