it started trading on June 29 rising 2.5% to about 28.9, and yet it comes out in one of my ports as if it used to trade around $101 and dropped to about $29 on Friday… Which obviously screws up all the technical indicators.

BTW the error is the same on both the old and new data servers.
Thanks, Z.
It’s a spinoff problem. We should be getting a cash-equivalent dividend from Compustat which should the price chart smooth. Reuters handled this with spinoff-splits which is also missing.
We will add logic in the future to automatically exit positions about to spinoff. We believe this to be the best solution to the mechanical approach since companies do not restate nearly enough historical data to make ratios meaningful (maybe a few years, and no quarterly ). So ratios after a spinoff are meaningless. Luckily the are relatively rare.
Thanks
