The document discusses the investment potential of trading strategies as assessed by their experience (ex), which reflects statistical representativeness based on trade history. It emphasizes that more trades lead to more reliable results while providing tools like the ex badge and leaderboard to assess and improve traders' ex levels. Additionally, it encourages community engagement for knowledge sharing and improvement of trading strategies.

2. Why is Experience (Ex element) investable?
•
Rational Investors invest if BOTH of the following conditions are met
1. Past returns were sufficiently high, on a risk-adjusted basis, AND
2. Past returns were not achieved randomly
•
The statistical representativeness of a trading history is essential to rule out luck.
With no further data, a strategy with 10,000 trades and positive returns is more
representative than a strategy with just 10 trades (and the same returns)
•
That’s why Experience matters. The results of a given strategy are more reliable
for an investor the higher the statistical representativeness of that strategy’s
trading history

4. “Ex” – What is it?
“Ex” measures how statistical representative a strategy’s trading history is
(this badge helps to rule out luck as a source of returns)
•
“Ex” is measured in TS periods. 1 TS period ≈ 1 month of active trading in a strategy
•
The highest level of statistical representativeness is reached when a strategy contains
12 TS periods
•
The diagnosis on TradeSlide is carried out taking into account the last 12 TS periods in a
strategy (i.e. in a strategy with 16 TS periods, only the last 12 periods are taken into
account)
•
Two strategies with the same number of TS periods have the same level of statistical
representativeness, irrespective of their trading style (scalper, swinger, etc.)

9. Improving Ex
•
Ex is an “easy” TS Element. It “only” takes time in the market to improve
• You’ll make valuable mistakes that will discipline your “gut”
• Only time allows you to formulate and optimize your strategy
•
Ex CANNOT be increased “artificially”
• Multiple simultaneous trades in a single asset are GROUPED into 1
position and only contribute to Ex as 1
• Multiple simultaneous trades in positively correlated assets: again only 1
independent trading decision (would a good trader open simultaneous
trades in positively correlated assets anyway??)
• Total count of trades is MEANINGLESS – Ex is ONLY driven by TS
positions (see next slide or Trading Journal for an explanation)
•
So: focus on all other elements. Doing this will clock hours in the market for your
strategy, and your Ex will build up. Investors will know that you’re more than a
lucky Monkey!
