Yes, I am making progress with your excellent importers on CSV, but for etrade OFX, I did not know how to change this block to work for etrade:
[fidelity]
type = ofxget
cmd = %(ofx_pre)s <your_username> \
--useragent randomstring \
--password $(pass financial/fidelity) \
fidelity \
-i <accnum1> \
-i <accnum2> \
> %(downloads_dir)s/fidelity.ofx
