I've been anxiously awaiting other people's answer to your question about how to best select trading indicators, but I see there hasn't been many takers. So let's "turn this question around" so there is a possible methodical answer to your question.
Wealth-Lab's strengths lie with measuring the performance (e.g. Profit-per-Bar, Net Profit, Recovery Factor, positive Equity Curve slope) of strategies,
not trading indicators. That's because trading indicators do
not determine performance--trading strategies do. So how does one pick the best indicators? Well, you work backwards. You let Weath-Lab identify the best trading strategies via their performance metrics, then identify which indicators those strategies successfully employ to be great. Not the answer you were hoping for, but at least it's the truth. Some related thoughts:
Wealth-Lab breaks its indicators into three groups: Standard (using Wealthlab.Indicators), TASC (using TASCIndicators), and Community (using Community.Indicators). The Standard indicators are the prototype indicators, which are time tested. You should master them first. The TASC indicators have all been publish in
Technical Analysis of Stocks & Commodities magazine, so they have undergone some reviewing for usefulness. The Community indicators are either notable indicators not published in
TAS&C, or specially requested by a Wealth-Lab user.
The bad news is that these indicators aren't grouped by purpose--and they should be--so you can intelligently pick which are most appropriate for the needs of your strategy. Probably the best advice here is to buy a book that groups all these indicators
by purpose. (I've done some of that myself manually, and it's a "work-in-progress" personal project that has been ongoing for four years.)
What I do look for in an indicator is one that ...
1) ... divides out (or normalizes out) the market noise with its denominator. Yes, that means you need to get familiar with their calculation. Examples of such indicators are CADO and CMO. The Kalman filter indicator has a nice example of employing the CMO indicator.

3) ... incorporates
both price and volume action together since both are important. EMV, VWMA, VMACDH, MFI, NVI, VZO are examples.

It is possible to interface Wealth-Lab to R to do exactly this (say with a logistic regression, multi-variant regression, principal component, or discriminate analysis). You might want to followup in this discussion topic.
