Today's P&L: about $9500
The profit from MBTrading should be around $1600, not $4180. MBTrading calculates realized daily P&L using yesterday's closing price as the cost if you have an overnight position. In today's case, this approach exaggerates my profit because I set up that position at a premium price in the after-hour market.
Total P&L for my 1st week of May (excluding Monday): about $21,000
Tuesday: $200
Wed: $3900
Thursday: $7400
Friday: $9500
