Uhm... I guess all of them are in the platform. You need to log into your account, enter the platform and there will be all indicators you can utilize freely.
Actually, the most demanded ones like moving average, relative strength index, maybe some oscillators are available here. Bollinger bands ae included and so on. Check out the platform, or reach out to the customer support team, but I don't think it's a good idea.

Well, since you can run with METATRADER4 there, you are going to be able to use the wide list of indicators brought to you by the software,

Oscilaltors,
Relative strength indexes (RSI)
Ichikomu clouds
Gator oscillators
Fractals
Commodity channel index (CCI)
Average true range
Money flow index (MFI)
Moving average convergence divergence MACD
Stochastics
Williams percent range
Parabolic SAR

Are just a few of them to count, the whole list is pretty exhaustive so i cant count all of them, but this is what comes to my mind
