Your notation for splits is backwards
When you notate a Split in a chart, you have it backwards. For instance, look at the MAX chart of CIEN. In 2000 there was a two for one (2/1) stock split, you have it as 1/2. Then during Sep of 2006 CIEN had a one for seven reverse stock split (1/7). You list it as 7/1.
All of your adjustments in the price scale appear to be correct, you just note the split wrong (i.e., backwards).

Hello Robert,
On our site 2/1 means 2 to 1, i.e. 2 shares became 1 share.
Hope this information helps!

According to Ciena investor relations:
Ciena had a 2 for 1 stock split in which shares became actively trading on September 19, 2000. Prior to the split, on September 18, 2000, Ciena's stock closed at $207.00.
Ciena had a 1 for 7 reverse stock split which became effective at 5:00 p.m., Eastern Time, on Friday, September 22, 2006. When the stock opened on Monday, September 25, it began trading on a split-adjusted basis and closed on that day at $29.68.

A couple of weeks ago I reported that your notation for Splits is backwards. You show 1/2 (one for two) when you mean (2/1). I told you to look at CIEN as an example.
I see that you closed this report as "Completed" with this post:

It's still like that.
