Darvas Vs. Modified Buy & Hold for ETFs

See: http://instigator928.blogspot.com/2009/09/kagi-3-line-break-renko-tna-charts-may.html
The modified buy & hold strategy related to complex NASI tops did better than the Darvas Boxes. The latter would still have a TNA position, whereas the NASI-related technique would have liquidated positions on September 23rd. The complex NASI tops were predicted somewhat by Darvas Boxes (see: http://instigator928.blogspot.com/2009/09/tna-darvas-sell-boxes-complex-nasi-tops.html) and was predicted more often by weekly equivolume consolidation (see: http://instigator928.blogspot.com/2009/09/tna-weekly-equivolume.html).
