Fred,
Using the following code it is possible to "set date ranges" in AFL
(similar to AA) and have single stock Equity results incorporated in
the Title as Herman required.
Buy=......//your rules
Sell=.....//your rules
Eq = Equity(0,3,1070702,1080515);// Start July 2, 2007 Finish May 15,
2008
Plot(Eq,"Eq",colorblack,styleline|styleownscale);
Tile=....... +"Eq"+eq;
Herman started this thread about Traders trying to make money. No one
challenged his comment about 90% of Traders not being programmers.
The other 10% might have the motivation to go through the steps
neccesary to complete a single stock backtest etc but most traders
seem satified to visualise the price action through their charts.
Portfolio backtesting is just too complex for the majority of Traders.
For those Traders struggling with the merits or otherwise of
backtesting maybe adding some basic results to the chart Title, such
as Equity, might be a positive step. Keeping it very simple was, I
believe, Herman's aim.
