Consistent with a client’s investment objective, the Advisor may enter into guarantee close agreements with certain brokers. In all such cases, the agreement calls for the execution price at least to match the closing price of the security. In some cases, depending upon the circumstances, the broker may obtain a price that is better than the closing price and which under the agreement provides additional benefits to clients. The Advisor will generally distribute such benefits pro rata to applicable client trades.
Currently, Bitcoin futures have very high margin requirements. The Cboe requires 40% of the notional amount for maintenance margin, the CME requires 43%. Your broker will likely require more than that. The culprit behind these high requirements is Bitcoin’s high volatility—until that calms down the exchanges will protect themselves by requiring a bunch of up-front money. If you don’t come up with the money for a margin call they want to close out your position without leaving a negative balance.

In the normal course of business, a Fund enters into standardized contracts created by the International Swaps and Derivatives Association, Inc. (“ISDA agreements”) with certain counterparties for derivative transactions. These agreements contain, among other conditions, events of default and termination events, and various covenants and representations. Certain of the Fund’s ISDA agreements contain provisions that require the Fund to maintain a pre-determined level of net assets, and/or provide limits regarding the decline of the Fund’s NAV over specific periods of time, which may or may not be exclusive of redemptions. If the Fund were to trigger such provisions and have open derivative positions, at that time counterparties to the ISDA agreements could elect to terminate such ISDA agreements and request immediate payment in an amount equal to the net liability positions, if any, under the relevant ISDA agreement. Pursuant to the terms of its ISDA agreements, the Fund will have already collateralized its liability under such agreements, in some cases only in excess of certain threshold amounts. With uncleared swaps, a Fund bears the risk of loss of the amount expected to be received under a swap agreement in the event of default or bankruptcy of a swap agreement counterparty. If such default occurs, the Fund will have contractual remedies pursuant to the swap agreements, but such remedies may be subject to bankruptcy and insolvency laws that could affect the Fund’s rights as a creditor. Thus, a Fund will typically only enter into uncleared swap agreements with major, global financial institutions that meet the Fund’s standard of creditworthiness. The Funds seek to mitigate risks by generally requiring that the counterparties for each Fund agree to post collateral for the benefit of the Fund, marked to market daily, in an amount approximately equal to what the counterparty owes the Fund subject to certain minimum thresholds, although the Funds may not always be successful. To the extent any such collateral is insufficient or there are delays in accessing the collateral, the Funds will be exposed to the risks described above, including possible delays in recovering amounts as a result of bankruptcy proceedings.
Total Return Swaps. Total return swaps are used either as substitutes for owning the physical securities that comprise a given market index or as a means of obtaining non-leveraged exposure in markets where securities are not available. “Total return” refers to the payment (or receipt) of an index’s total return, which is then exchanged for the receipt (or payment) of a floating interest rate. Total return swaps provide the Fund with the additional flexibility of gaining exposure to a market or sector index by using the most cost-effective vehicle available.
