Okay it sounds like you're more pre wrath than actual mid tribulation.
traditional mid trib has usually positioned the rapture to be at the midpoint of the 70th week, when the abomination of desolation takes place, which I suppose until the abomination of desolation actually takes place since that's the key sign Jesus gives, you don't know you're in that week for 100% sure, but it is kind of a specific day, if anyone can correctly time the covenant with many they could potentially know the exact day I mean.
Pre wrath is more after the midpoint/abomination of desolation there's the "Great Tribulation" that Jesus talks about in Matthew 24, and sometime during that 3.5 years the sun and moon will darken (the 6th seal in Revelation 6) and the rapture takes place then. So it's sometime during the middle of that 3.5 year period after the midpoint.
Does that sound close to you, or is it more that you believe on the day the Antichrist declares himself to be God in the temple boom, we're out, on exactly the midpoint?
