4 hour commodity time frame with Manshi RT in Meta Trader 4?

Hello,

I plan to use a 4 hour time frame for trading commodities.

I've signed up for one months trial of Manshi RT but the charts available for trading commodities are M1,M5,M15,M30 and H1 because only offline charts are available through Manshi RT.

How do I trade on a H4 time frame with Manshi RT on Meta Trader?

I can install a trial of Ami Broker if it is possible to have 4 hour charts on AMI Broker through Manshi RT.

I got AMI broker to display 4 hour charts with Manshi RT.

Unfortunately, the Manshi RT data feed for GoldM is inaccurate by over 200 rupees for data on Jan 5th and earlier. I tried Manshi RT because the data feed from Sharekhan's Trade Tiger was inaccurate (I noticed the discrepancy on Sunday) but today, the data feed is fixed on Sharekhan's TT (I had to refresh the graph and I'm not sure what the equivalent of that is for Manshi RT.)
