Wealth-Lab Developer has features such as order slippage and variable commissions to bring trading simulation as close to reality as possible. Likewise, your task as a trading system designer is to express your system in C# code that validly recreates security orders as they would have been and will be executed in real life. Bar Definition
A bar is any interval of time that has an open, high, low, and closing [...]
[...] to create a Pullback in an Uptrend entry. For instance, in an established uptrend, wait for a three bar pullback and
enter at stop $0.10 above prior bar high. However, the Rule Wizard doesn't seem to have "Buy at Stop" rule desired. Solution:
You can get pretty close by starting with these rules: BuyAtLimit (High)
- Moving Average is trending up (Moving Average group)
- Price decreases a consecutive number of bars (Price (or Volume) group) ..and add an exit (if you only want a screen, see Techniques > Creating a Screener in the WealthScript [...]

[...] trades when the cycle turns up within the threshold zone and exits on a closing profit of 4% or after 5 bars. The time-based exit was chosen purposely to be a ¼ cycle to exit before the next turn down. The Strategy produced a slightly-positive win rate and raw profit factor for the last 6 years of trading on the Dow 30 and Nasdaq 100 index components.

[...] quarter is 13 weeks, so it’s roughly a "3.25 times Weekly" or "16.25 Daily" scale (given there are 5 trading days in a week). Since Bi-Weekly and Monthly scales contain 10 and 22 trading days (respectively), it doesn't look like the new scale would be that necessary to bring much difference from either Bi-Weekly or Monthly. Out of the box, Wealth-Lab does not support custom chart scales like Bi-Weekly or Half-Quarterly. Alhtough the scales like Bi-Weekly or Quarter Quarterly could be accomplished fairly easily using the EOD Scaling Provider (a Wealth-Lab addon), [...]
Traders' Tip text We programmed the long-only Tr&nd stop strategy for Wealth-Lab 5 in C#. You can use the sliders to adjust the Period and atrFactor Strategy Parameters to eyeball an optimization, or using WLP 5.4 you can now run full Exhaustive and Monte Carlo optimizations. A portfolio simulation ($5000 size, $8 1-way commissions) on the Dow 30 symbols over the last 6 years yielded the 2-Parameter optimization curve in Figure 1. Figure 1. While the optimization didn’t inspire confidence in the strategy’s stability over a wide range [...]
