Back Testing

[tanita]

I´m lookimg for the formula for a backtest with
the RMI. (3,8)

1. if RMI > 80 go LONG
2. if RMI < 20 go SHORT

Can someone help me, how I provide this formula??

Thanks

I found two versions of the RMI indicator both coded by TS Support and available at their site and presumably in their group at FileShare.
Given that you were indicating two variables I took their alternative version of the RMI (which allows for that) and added the strategy as per your message.
The system goes long if RMI moves above 80, sells to close the long if RMI comes back below 80, goes short if RMI moves under 20 and covers shorts if it goes back above 20.
The entries for the strategy are on the Open of the bar following the one that generates the signal.
The enclosed image shows you how the indicator should appear.
Hope this helps

Here is a variant of the same strategy.
In this version the Buy and Sell are on a breakout of the high or low of the bar that generates the signal.
As of now the breakout is set for one tick of ES (0.25) but can be changed in Lines 94 and 99 of the formula to suit your needs.

Hi,
this formula ( test-rmi2-market) was exactly the correct one.

Cordial thanks and a nice day

Backtest Williams%R

Hi,
I´m looking for the formula for a backtest with
the Williams % R(14)

1. if Willi < -20, go LONG
2. if Willi < -80, go SHORT

Can someone help me, how I provide this formula??
Thanks and a nice day

The attached efs should do what you are asking

Backtest/ efs

Hi Alex,
thanks a lot.

Is there the possibility of a combination of three Indis as baking
test/ efs??

1. Go Long if (only)

Williams %R > -20 + Aroon up = 100 + RMI > 80

2. Go Short if (only)

Williams %R < -80 + Aroon down = 100 + RMI < 20

Thanks for your help and assistence

It is possible, but setting up the formula to calculate all three indicators and/or cross reference them is beyond what I am available to do at this time.

Backtest Time Template

Hi,
in the baking test time Template cannot be adjusted and
computed the daily end. (Intradaytrading!)

If one accomplishes a week test or a monthly test, the program further calculates and takes the time of in the evening to the next tomorrow as new order!

If you are saying that the Strategy Analyzer (ie Back Testing) does not close trades at the end of each day when intraday trading then that is correct. You need to specify that in the efs.
There are a number of examples that have been posted in this and other forums.
I agree though that it would be preferable if there were some sort of built-in routine that one could easily call when setting up the strategy.

I am not sure I fully understand your second point.

Back Test Times

Hi, Alex,
it is difficult to find out.

My trading houres are: 9:00 -19:00 and i start always with a new day on the same time.

A overnight position does not exist.

Nice and sonny day

Below are the links to a few threads that might provide some insight.

Note: In the last thread there is a formula which contains a section that closes trades at the end of a session

if i try to follow the 3rd link, because i need the codesample for close the trade on the daysession end, i get the following message:

That link is to the Beta Forum for which you need to be registered.
Anyhow I just lifted the formula off that thread and am copying it here.
