I hope none of the devs gets offended by this but im totally serious about it

The way JForex is implemented is brilliant and totally useless at the same time. Why? Well using Java was the brilliant part, the way Indicators are implemented the really "questionable" part. A Metatrader clone based on Java with Java API would have been a much better idea. Guess why everone trades with jforex but charts on metatrader? Not because everyone is too lazy to implement the indicators in jforex. In most cases its just not possible because of the IIndicator shortcomings.

IIndicator is so crippled that it's almost useless for serious indicators. Either there should be access to IHistory within IIndicator or there should be a way to attach a Strategy to a specific / multiple charts since strategies overcome all of the major shortcomings of IIndicator.

e.g.

- multi timeframe indicators:
- it's virtually impossible to do proper mtf inidis with IIndicator since multiple input streams with setperiod hang jforex once u switch to a higher timeframe also you cannot call other indicators properly in higher tfs because of related problems
- it's perfectly possible with a strategy since you have got access to IHistory, can fetch whatever symbol / pricefeed / timeframe you want on any timeframe and do whatever you want with it + call any indicator in any way you want

- multi color indicators

- I'm sure a ****load of other problems mostly related to both of the above mentioned problems

So please let us drop metatrader in favor of JForex by either implementing IHistory access in IIndicator or give us the possibility to attach a Strategy to a specific / multiple charts. Thanks for listening. The mentioned problems would make JForex the great thing and absolut metatrader killer it should be.

Why its not possible to implement access to ihistory in indicators?

I guess Duakscopy did have a simple interface in mind when they designed IIndicators being wrapped around ta-lib.
The result is that it does come with design limitations, especially when you'd like to chunk up one level and compare data of different timeframes, currencies and have flexible access to historical data on a metalevel.

I agree, it would be very beneficial to add a new layer to the api that gives users the flexibility to freely retrieve, combine and compare indicators of different timeframes and currencies in the indicator logic itself.

Best, RR.

@DukasCopy: Are there already any plans in place to update the indicator model or are you already working on an extended model? If so, would you be willing to share information about the roadmap for this development? Any feedback would be very much appreciated. thx a lot.

We are already working on it.

Thanks a lot!!!

Hello Dukascopy,

is there any progress to report on the issue? Ideally you would have a roadmap and a schedule.

Regards,
Marcin
