Yes I prefer Linear charts as well. I can switch to either and have printed off charts with both and am sold on the Linear charts. I had read somewhere that Logarithmic charts were better but this entire percentage gain stuff tends to exaggerate most everything especially a chart. I gave a guy an example of percentage b.s. once: your $100 stock falls to $10 losing 90% of its value. Then it rallies from $10 to $20 which is up 100%. So what are you going to do with the 10% profit you just gained,LOL. That made the point about percentage change b.s. well I thought. Good to use to make a point only. Like the SPX doubling since March/09 but still being well under the 2007 highs.
As far as AD goes I agree a drop back to that 1.01 breakout pt high of Nov/Dec/Feb and March would be the buy point. That usually is the best buy point on a Daily chart. I suspect smart money is finished with this 11 day run up and will be looking to buy down there. Note how the run up began 11 days before the seasonal buy date. I need to spend some time on that again and start following smart money rather than reacting to them. Don't know if AD will get all the way down to 1.01 as April is the strongest seasonal month of the year for AD. And then from early May it comes down just as fast. Might just be out of time on this.
