Hi David,

I've been using TradeSim for quite a while now and I'm very happy with it.

Can TradeSim display the equity chart in semi-log format? If not, this will be a nice feature to have...

Thanks and regards,

Kumar

Do you mean profit on a log scale?

Hi David,

I meant Total Equity ($) on a log scale...

Regards,

Kumar

I would have been pleased also to find this Log tool in V4 ... :(
(may be I've not seen it ? ...)

nevertheless, great work you have done so far :)

I know it's been a while (2 years ;-) since Kumar's original request, so this may be a little of a stale topic, but I came to the same conclusion independently and it's an easy thing to code (;-) so I thought I'd pipe up.

When back-testing a good system over a significant time, the proceeds of the first years are scaled down into insignificance. A semi-log scale would be very useful. There's also an argument that it just makes more sense.

[For those unfamiliar with the term, a semi-log scale is most often used to refer to a log scale on one axis and a linear scale on the other. Typically the Y (time) axis is linear and the X (in this case, equity) axis is log, so that a doubling of money in a year results in the same increment up the Y axis regardless of where it starts from!]
