Insufficient Data/Long Strategy Calculation Times

Postby deltastrike » 30 Jun 2015

I'm having some trouble with Renko style charts as far as longer strategy time-frames are concerned, as well as Walk Forward Optimization.

My current settings are:

ESU5
Renko Chart Type (1.25 Fixed Price, 3 Minute)
24/7 Session
3650 Days Back from current date
Signal Max bars back is 5000 (can't go beyond that without problems)

My problem is if I set the MaxBarsBack > 5000 then the signal never calculates, it hangs at "Calculating" for a very long time without doing anything.

Also, like I mentioned, the Walk Forward Optimization doesn't work either. It keeps throwing an error that there is not sufficient data for optimization.

Any idea what's going on here? Are there limitations with Renko charts?

You have fallen into the same trap that many newbie fell into...

You have misunderstood the definition of Maxbarsback.
The term "maxbarsback" is a misnomer,
it should really be called MinBarsForward.

It defines the MINIMUM number of bars required to calculate your indicator properly.
When you load a study into a chart, MultiCharts will skip the number of bars defined by MaxBarsBack before making its first calculation of your studies.

eg. if you have a 25 period moving average, the MaxBarsBack will be automatically set at 25. MultiCharts will start calculating the moving average at the 26th bar, because that's the MINIMUM number of bars required to do a proper calculation of a 25 period moving average.

My short answer: Forget about Renko... it is ok for manual trading.
Renko is not easily applied in an autotrade environment.
Don't ask me why or how... it is a long story. I can write a PhD thesis on it.
If you want to know, you can keep on experimenting.
Do a search on this forum, there are plenty of previous discussions.

YMMV

Thanks for your feedback...although I am very curious as to why you think Renko won't work in an automated environment (bullet points perhaps?).
