A Day in the Life of a TradeStation App: Moon-ES


Earlier this week highlighted automated strategies. They’re one of TradeStation’s most important features, putting the power of machine-think to work in your own portfolio. In addition to letting you create your own strategies, TradeStation has a thriving community of professional developers who sell their products through the TradingApp Store.

Today we wanted to highlight a popular system: Moon-ES. It uses Bayesian probability math to determine entries and exits on E-mini S&P 500 contracts (@ES). Here’s what it’s been doing in the last few days:

MOON-ES 3/9/18-3/14/18. Buys and sells marked in green and red.

This screenshot clearly illustrates how Moon-ES both caught Friday’s rally and then reversed as the index stalled on Tuesday. It can generate several trades a day, and triggered 764 times in the last year. TradeStation Strategy Performance Report shows that running this App in Full Auto mode can be a very successful strategy.

Some customers are new to futures so here’s a quick explainer on how they’re often used. @ES is the generic symbol for CME’s S&P 500 “E-mini” contracts — the most popular futures out there. The full symbol changes every three months, but you can always find the basic product by adding @ to its root.

Futures are different than stocks or options because you “go long” or “go short” without ever taking possession of anything. Instead futures commit you to buy or sell in the the future based on the price at the time of the trade. If you “go long” at a low price and it rises, you make money because you’ll be locked into buying at a cheap price in the future. The opposite is true if it goes down. But even that’s hypothetical because these contracts settle in cash. You never take possession of anything. You just make money or lose money.

The other important thing is that each contract has a unique value multiplier. This multiplier determines the cash value for the contract. For @ES, it’s $50. Visit our Market Knowledge Center for more on all the various futures contracts.
