The prelaunch funding model differs from regular products in how the index is provided. Rather than an oracle, it is computed. The other parts of the model are the same apart from the following constant values.
FundingInterval set to 24 hours
Clamp set to 0.005 = 0.5%
BaseRate set to 0.00025 = 0.025%
Prelaunch index
Index = ema(FundingMarks, PrelaunchWeight)
computed every TickInterval
ema is exponential moving average
PrelaunchWeight is the EMA weighting
set to 2 / 2881
FundingMarks is list of previous FundingMark every TickInterval
