Aimagic,
Once, again great job on the minimum buy/sell coding! I like the way you made it adjustable as well. The speadsheet is nearly identical in functionality to the X_DEV program, so I can't thank you enough!
Those are some great results on CELO!
The minimum $ amount is there to prevent very small $dollar amounts from being signaled. Doesn't make sense to trade $5 - $150 or whatever if your portfolio size is over say $20,000. But to each his own. Now that you have made it adjustable (like the program) the user can choose whatever suits his needs.
The minimum signal is something I brought over from the AIM algorithm. It is extremely useful for tuning the X_DEV algorithm to produce the best signals. I could probably describe the intricate math that causes this functionality but I doubt it's necessary. It would be like describing how the intricate electrical components of a TV function to produce the signal. I rather just turn the damn thing on and watch a movie...lol.
As far as choosing which assets are best for X_DEV. I just go with high quality high volatility plays. I need to have confidence the asset will not collapse into obscurity in a black swan event or a prolonged bear market.
