Most DMA or Direct Market Access platforms are just that. They are used to excute the trades only and give volume on the 10 price levels of Bid/Sell. The volume will be FX contracts. A brokerage fee is then charged eg $3.50 per contract of $100,000

A charting pagkage is then bought or subscribed to on the side.

Trade Navigator for example is purchased then a reasonable feed fee is charged per month.

CQG is the best charting platform and you get to pay just under $1000 per month for the experience. Chart timeframes start at yearly, quarterly, monthly etc down to tick

GFT are pretty good for learning, mini contracts $10,000 or $1 per pip of movement. no volume though as they are a Market Maker, so your spread will be the brokerage and the spread widens and closes at different times of the day, this needs to be checked especially if trading away from the main 7 currencys, but if you can't make money on EUR/USD, USD/JPY or GBP/JPY if you like a more lively match then the odd pairs won't either and the large spread will quickly take the shine off.
