I like the film index and it is doable.

I spent a couple years of my free time digging deeply into motion picture industry numbers, and industry data (often questionable) usually comes from only a few reputable sources.  Box office opening weekend is a key metric for the industry as it can make or break new talent in the industry.  Can Bitshares handle discrete event prediction markets?  Huge opportunities for sporting events.

I would like to agree .. but I don't know how often people are "updating" their feed scripts .. also some delegates still don't publish feeds at all .. (old story)

Where can I read about the preferred or official feed format and the technical details of pegged asset implementation?
Would a comprehensive market data collector be advantageous to the community?

I am glad to see others interested in the index approach.

Just some thoughts:

    While it could be run using the CFD model very safely, I think an Open Transactions or Hyper Ledger as a ledger for a reserve to  actual tokens is the most legit way to go.

    Save CFD's for SPY for DJI and NASDAQ.

    The key to keeping a reserve is limiting the redeemable time from entry of the assets as well as the value flow in to maintain calm markets.

Crypto coin and asset Indices:  Tradeable Indices without market and managerial risk

Value Proposition:
    Treating Blockchain as DACs creates a reference point to treat BTA and networks as an industry.
    Blockchain Industry following indexes should be built on industry tools and systems
    Bitshares provides the most advanced distributed exchange and application specific ledger to lead this type of operation.
    Bitshares becomes more relevant inside the blockchain technology ecosystem
    Bitshares provides assets and tools relevant to those who want to safely increase their blockchain finance usage
    An index fund and exchange traded fund are among the tools of modern finance that Bitshares can operate to increase utility among the block chain technologist and believers.
    External exchanges are still needed for market price discovery and liquidity
    Industry tracking investment vehicles could increase awareness among mainstream non-adopters of blockchain technology as a fair risk asset better suited to personal style and risk profile.

Bitshares Competitive Advantage:
     Bitshares has "contract for difference"  (CFD) smart contract abilities which is the foundation for bitAssets.
     Using CFD market mechanics long and short positions that track the value of the underlying asset without user risk to managerial fraud or mistakes and market liquidity squeezes.  Users can hold or short and asset that tracks the fair trade value of the underlying assets.
    Bitshares also has very fast block times providing for near trade time exchanges of value that most other blockchains cannot provide.

Potential Competitors:
    Ethereum project provides CFD capabilities and will be open for any user to create CFD contracts at will.


Proposed Asset Lines:

    Marketcap Traditional Index 
        suffix: MTI
        Traditional Marketcap Weighted Indices

    Marketcap Broad Index
       suffix: MBI
        Weight limited market cap based index to provide broader exposure to the over all market
   
    Volume Cap Index
        suffix: VCI       
        High Marketcap Low Trade Volume

    Equal Weighted Index
        suffix: EWI

    Price Weighted Index
        suffix: PWI

    Sector Specific Assets:
        Strong Privacy
        Distributed Apps
       

The above asset line provides most of  the major traditional methods for index composition and allows for varying levels of exposure to the current markets.

To make this easier for delegate participation reference python libraries to pull data from data aggregators and exchanges will be provided.
