Since shares CFDs are traded on margin (ie. borrowed money from Juno Markets), financing charges will apply. Positions held open after the close of market (5pm EST) will incur a financing charge based the market demand of the underlying coin. Finance charges can be found by checking the specifications of each coin in the Market Watch window.
Finance charges are quoted based on annual interest rates. To calculate the daily rate, take the interest rate and divide by 360. For example, if the finance charge for BTCUSD is 10% and BTCUSD is trading at $50,000, then the annual cost of holding 1 BTCUSD position is $500 USD (50,000 * 10%). Therefore, the daily charge is $1.37 (500/360) per BTCUSD contract.
Juno Markets charges 3 days of finance charges or swaps for all positions held past Friday at market close.
