Hi Steve,
Is there any reason why you are using a bar count of 50 in the sixths indi and not 120 as Nanningbob uses in his indi?

It's been a long day so I could be missing something

Only because 50 was the default when I downloaded the indi, and it appears to be working.


Should it be 120?

Hi Steve,

I've just re-read the 'NB 4H TRADING SYSTEM V. 5.0 PHILOSOPHY.doc' document from Nanningbobs thread and in this it recommends using a 4HR chart showing 1 months of price action. The sixths are then calculated from this. By my reckoning this will be 120 4HR bars.

I will have a play around with different settings to see what difference it makes.

Cheers PJ. Thinking about it, 120 does make sense; sq's indi defaults to this as well, for the same reason.

Steve,

1st pic shows results for 2 years backtest on UJ M15 using 192 bars (48 hours) & 720 bars (180 hours) as trigger points. So 192 bars is the best - right?

Hi Macman,
Sorry if this is dumb question but which EA were you using for these backtests? The only reason I ask is that I can't get anywhere near the results using the EA in post 1. Also, it looks like the results you posted show the lot sizes changing but the EA in post 1 has a fixed lot size.

Hi PJ,

The point of the post was to illustrate how using the same entry condition (number of look back bars) does not work very successfully if applied across the board to all pairs.

The EA used in the tests is an earlier version of NanBob's strategy available in the NanBob thread.

Mac, I thought I saw somewhere that you were using 168 bars. Is that no longer the case?

168 bars on H4 gives me a look back history of 28 days (168/6), which I do still use.

There are 168 hours in a 7 day week, so doesn't this mean you are looking further back in time than you intended, given that trading is a 5 day week thingy?

Probably best to set a default at 120 bars look back on H4 (20 trading days) & adjust this as we go along.

In a way it is irrelevant; I do not see how to use Bandwidth to spot a bulge, so the default effectively turns it off. I have not given it much thought either - I am learning to trade this stuff manually and having a lot of fun doing so.

I have made one major change.

The NB MACD is a visual illusion that works brilliantly for manual trading.

Using the mathematically-accurate StochMacdSqualou for manual trading results in most trades not being taken because it so rarely passes the 85/15 levels - the reason this robot has taken so...
