Traders' Tip text We took this opportunity to add both the Bollinger %b and the Sylvain Vervoort’s smoothed version to Wealth-Lab’s TASCIndicator library for Version 6. The WealthScript code shows how to access and plot both indicators, their standard deviation bands and parameter sliders. We have to wait for the author’s follow-up article for the indicator’s suggested use in a trading strategy; meanwhile, we look for price divergence as one would with the traditional %b indicator. At the time this went to print, the Nasdaq 100 appears [...]

[...] insufficient funds. Why? It is possible in Raw Profit mode when a) Fixed Dollar sizing is selected and b) the selected position size is not enough to purchase even one share of the instrument. It can happen with with higher-priced instruments such as indices. Consider this example: your position size is $1,000 Fixed Dollar, and at the time of entry the security's price exceeds the position size e.g. is $1,100. There are two options: switch to Fixed Shares or increase the Fixed Dollar position size. How do I implement volatility position sizing? Position sizing based [...]

[...] the test period to build indicators, known as "Lead Bars" in legacy versions of Wealth-Lab, affects B&H comparisons and performance metrics sensitive to changes in start/end dates. Imagine an indicator that takes a while to build up - like a 200-day moving average. The Buy & Hold starts immediately while the Strategy has to wait for at least 200 bars. Should Lead Bars exist, they would provide a slightly more accurate statement of performance over the test period when backtesting such Strategy. Fortunately, there's a script-based workaround for situations when there's [...]
