Interest rates files are most often sparsely populated.  The time between any given testing date Trading Blox will encounter is to use the most recent previous rate-date for Forex Carry, Interest Earned, and Margin Paid purposes.

 

The data in these interest rate files is dependent upon the user to update these files manually and as new interest rate records become available.   To get the best value to use, it is best to get the carry cost data from your Forex Broker, or a known Forex Broker like Oanda - Interest Rates.

 

In the earlier portion of the Interest Rate Files, there are many records where there is only one interest rate for each of the very early date records.  Those single interest rate value are a Lend Rate.  The Borrow Rate can then be computed by adding 0.5% to the Lend Rate. This calculation method is included for historical reasons.

 

The best approach is to use two rates so that the Lend Rate and Borrow Rates are in the interest rate files.  The first column is the Lend Rate and the second column is the Borrow Rate.  These are the rates are used for Forex Carry costs.

 

In addition, the system wide currency rate files, USD_Rates.txt in most cases, is used for Interest Earned and Margin Paid. The Lend Rate is the Interest Earned and the Borrow Rate is the Margin Paid, for any given date.
