gaps

Howdy all , looking for comments on the trading gap on XJO and the spi from close of trade 21st Jan to open in the morning on 22 jan .

I use several different charts and one of them only records daytime spi so therefore we have a huge gap from 4797 to 4728.But on our providers charts we all know we traded down that night , neverthe less we are also given a gap on our XJO chart from 4728 to 4669 stil a good 60 points .

Now our hrly chart of the spi shows a double bottom with a possible projected target around 4610...........

Can anybody see any reason why we should cover our spi gap to 4797another 200 points .?????? Or do people think this is not really a gap at all as it was traded down during the night and just is shown as a gap in a daytime chart but doesnt really qualify ? However that still leaves us with a gap in the current xjo chart which must get covered one day surely .
Appreciate all comments, criticisims , witisisims and etc etc

cheers
