The Feb Correction:
This can be seen from the charts and it is self explanatory. Starting at the top of 14724, the 38.2%, 50% and 61.8% stand out as very important numbers to the 100% mark at 12316.
The March Bottom:
This number sequence starts from the bottom at 12316 and the top is assumed at 15675. With this in mind, the numbers work out really well. We see:
1. The 61.8% mark acts as the first resistance to the upmove.
2. The 38.2% mark acts as the first support to the upmove.
3. The 50% mark now acts as the support to the upmove.
4. The 61.8% mark now acts as the final support to the upmove.

The June Breakout:
This is actually the Magic Numbers in the 68.1% to 100% region of the 'March Bottom' chart. We see:
1. The 0% offers the first strong support to the breakout.
2. The 38.2% mark sees the close of the doji.
3. The 61.8% mark offers the final support to the breakout.
