I think the problem it is with "Tradeable" and the "Android". If you look into Android market there are a few apps, which allows you to trade in limited conditions. I am not satisfied with the minimum conditions, which offers other mobile platforms, that is why i don't call they "tradable" until you can't see your position in the chart and need to change your screen... this basic feature has the iPhone implementation now, which is the best trading terminal, what I saw.
I wrote on other forum, about other platform. The IT product manager, who plans the product and accept it, should get his money only and only he use his product daily as his customers will do. It will be instant platform improvement, guaranteed
Now at iPhone is relative simple, basically iPhone 3 and 4 has the same screen, resolution ratio, easier to implement, than in Android. With the Android there are a couple of "problems", screen sizes goes from 320x240 to... 2560x1600 huge scale. Screen size ratio it is not 1:2 as in ios , but many different screen ration, density.Please take a look at the bottom of page:
https://developer.android.com/guide/prac ... pport.html there is a table (Table 3. Various screen configurations available from emulator skins in the Android SDK (indicated in bold) and other representative resolutions.)
Dukas has an API -just started to dig they code I don't have a clean overview at they whole platform, but as I saw: they have written code with indicators and chart function, which can be called. I suppose, they use GDI to render and not OpenGL. And I think that is why fail so many Android clients. They will be extra slow, less features and so on.
If you prefer to connect to a desktop from your mobile with Teamviewer and do the trades on that environment, that means your mobile platform need to be improved. It can be your hardware limitations to do it, but in most cases not that the problem.
I don't use a toon of indicators, only 1 or 2 from this: EMA, SMA and BB, very rare MACD.
the first 2 indicators, shouldn't be a big deal to draw it, and usually those which can be drawn on the price chart. The MACD is under price chart, that is a different story. I think my Nexus One, (which is to old now for Google to give support with Android 4.0 ...) with OpenGL ES 2.0 will do a simple candle chart with those few indicators and see my 1-2 open position on the chart and TP, SL levels. I want very similar chart environment
in Android, which Oanda's FX Trade ( desktop) version. It is very limited vs JForex, but I have used like 2 years

The implementation if is from the broker side, it should cover the most of active phones.
According to Google:
https://developer.android.com/resources/ ... sions.htmland
https://developer.android.com/resources/ ... reens.html and
https://developer.android.com/resources/ ... pengl.html- it should be with OpenGL ES 2.0, Android 2.2 (or even 2.1) , and mdpi, hdpi phones targeted mainly.
It is not an easy task as it seems. Compared to a 2D game development, this one is harder, because no "Forex mobile platform engine" available as in the games.
I have sent a request to other broker too, which has Java platform I would fix a few bugs and add new features even for free, but didn't took me serious my propose. Maybe they policy restrict to be developer, if you are trader with live account, who knows. Or my third language: the English, it isn't enough for they...
As you can read above Dukas has started they platform development and should be ready. Not sure, why delay from the delivery date promised, but some bugs are really hard to detect and fix it, but Dukas should have more human and financial resources than me

I am glad for open API here, because I hope I will do a platform in 2-3 month (depends how much free time I have), which cover my basic needs. For me the hardest and most time consuming are the design making: logo, icons for buttons, formatting text input fields, skins ( they took like 80% of my time in last project) , since I am not designer.
Many of you probably will need some other indicators, other features which I don't and even mine will not be enough for you. I would like to see what features and indicators need others at Android platform! Please write here your device info ( model, resolution, OpenGL version) and features which would you expect to do at price chart!
