Both Market Delta and Cisco Futures offer excellent products. I would see the differences this way.
Market Delta provides the number of contracts traded at the bid and the ask and provides a nice user defined element to color the rectangles under the bid ask data to show the intensity of the move. Trademaven F3 and F4 charts not only show a visual of volume at price but color the bars to replicate a Market Profile distribution. To my eye, this is more easilt interpretable.
Trevor Harnett is an excellent trader and, at least at one time, the owner of Market Delta. It is an excellent product and, if their web site intrigues you, I'd take their free trial. Unless something has changed from when I was a subscriber, they don't have an equivalent to the TIE Trader Room with Charles Cochran.
Cisco has an excellent short and long course on Market Profile. I have taken the short course myself and was formerly a subscriber. Don Jones is exceptionally knowledgeable and does thorough research. He was one of the original providers, if not the original provider, of MP data from the CBOT. I would interpret their offering as more applicable to a swing trader. Again, there is no equivalent to the TIE Trader Room.
Cisco has a wealth of free information on their web site. I would also also suggest taking their free trial if swing trading suits you.
Both Trevor Harnett and Don Jones belong in the "good guys" category of quality people in this industry. Both are extremely knowledgeable and are of high integrity. I have had only good experiences with them and their products.
I see Trademaven as the most complete offering in the industry. Their charts are well designed and provide a wealth of information for the type of trading I do - short term swing trading and scalping. They are very visual and are the only ones that include a deceleration indicator, which is absolutely key to volume interpretation. Subjectively, I find Charles Cochran to be the most knowledgeable analyst I have experienced, and I have been in some rooms that had excellent commentators.
The only way a new trader will be able to make an informed decision will be to try out these excellent offerings and decide which suits their personality best. Again, subjectively, I prefer Trademaven. And as I have previously mentioned, I am an independent trader who is doing consulting for Trademaven. I could go anywhere and use any software. Trademaven is my choice.
