SPX 324 points/45 weeks

here is a chart I posted weeks ago.I thought 36 weeks was the top but it has basically traded sideways in a volatile fashion since then,with one false downside break.,This week is 45 weeks (1/8 of 360) and Monday was 216 days (144 x 1.5)
so the original Gann square has been extended by 1/8 in price and 1/2 in time
1740 seems an obvious target
