Clive, you have captured the essence of this "ladder thing" we have been discussing here, and I had discussed this with Don Carlson way back.
The ideal case would be for an asset that you knew its price was going to remain within a tight range, never broke out above or below that range, and that zig-zaged a lot.
As most equities do not behave this well as that I have resigned my self to having more than one scenario at hand and as the behaviour I would switch to a different trading scheme.
One more thing: Your Ladder typically is defined for the complete trading range while my and Don Carlson's ideas were focussed on more progressive trades as he price moves away form the Mid Point Price.
It would appear to me that your ladder is more easily programmed into an Excel Sheet. As yet I completely escapes me to get my "ladder thing" implemented other than to let Vortex AIM run its normal course and manually intervene to execute the trades that are shown on the "ladder picture".
Indeed, if trading costs are high then frequent trading on volatility becomes problematic. . .I had this problem years ago when Trading ASMI stock from Holland. It was only listed on the American exchange and each trade cost me a basic Fl.150 + other charges it was impossible to AIM small Holding Zones. But AIMING it I did and when I sold I had an Annual yield of 137%
So, AIMing with high trading cost work fine if the volatility is high and when using high-% holding zones.
