The problem in ami is that you can not draw vertical and oblique lines as per your wish. So I have tried my best to draw this chart, the diagonal line is 45 degree line, as all know that diagonal divides a square into two triangles of 45 degree each.
And you can see that all the price action is below that line.
Moreover, I have taken a lower point the bottom one in the chart and if you take the corner of square to your red candle the price will be even more lower to 45 degree line. (Though as per rules you can not draw angle as per your wish, it should be either highest post or the lowest point, as far as I know)
