20 Mar The Best Testing Method Ever
The Best Testing Method Ever
Mar. 20, 2023
I love everything about trading.
Except one thing.
I don’t love questions about the “best way to test”.
It’s like saying, “What’s the best grip to use for my forehand?”
There is no “best” grip. While some grips will put a permanent ceiling on your potential, many, many grips are perfectly okay.
The best grip is not some special concoction brought down from a secret pro in the Tibetan mountains. The best grip is the one that allows you to hit the ball in.
To have endless discussions about the pros and cons of western v. semi-western grips is pointless and makes me want to set myself on fire.
And trading is no different.
You can use Profit Factor, Return on Account, max drawdown, or max profit. Or a combination.
You can use the profit to drawdown ratio, Sortino ratio, or average trade size. Or a combination.
Or something else.
To discuss which one of these is best makes me want to stick my hand down a garbage disposal.
Because there’s only one thing that matters.
Watching it trade.
When you turn on a robot, what does it do?
Or, if you’re testing, build a robot and then watch it trade.
For months. Or years.
Watch it trade untouched for a long time. If it works, then it really works.
No ratios or out-of-sample configurations or Genetic testing tricks matter.
Does it make money or not?
Which is why I love going back to old systems. Old systems tell the truth. If it works after I write about it, then I get very excited.
So, with that in mind, here’s an old post from 2018 on the “Twitter Trend” method. You can read it HERE.
This system is overly simple and people who like to argue could definitely find 14 things wrong with it. It gets Long on a Daily chart when price is above the 100 SMA, RSI goes Oversold and then crosses back up out of Oversold. It exits when RSI closes into Overbought. No stops, no targets.
But the real question–the question that matters– is: how has it done since 2018?
In the post, I moronically used the AUDJPY. Who only goes Long in Forex?
The Equity Curve from 2005-2018 looked like this:
From 2018 to now, the Curve looked like this:
And here’s the Report from 2018-now trading 1 lot each time:
It’s still working.
I don’t need Z-Score or the Ulcer Index. I just need to know if it’s worked going forward.
And, astoundingly, it has.
Here’s the really crazy part. It works even better on other instruments.
And we’ll look at those in the next Newsletters.
