[RV Analysis] Added “Vega3M Neutral” weight
In RV Analysis under the “Weight” drop-down, once traders select “Vega3M Neutral” they can weight the trades by weighted vega (3M).
Calculation for Vega3M = Vega * Sqrt(0.25/T)
For example, -1/1 weight of 3m1y and 1y1y
1y1y has 1 vega and 0.5 weighted vega
3m1y has 1 vega and 1 weighted vega
Therefore: Vega 3M weight should be -.5/1 instead
* vega3M weight should fix spreads to have longer term leg as 1 or -1 and fix flies to have belly as -2 or 2 (in the fly, 1 belly vs each wing should be vega3m neutral)
