Most traders are on a wild goose chase...
Spending 100s to 1000s of hours back testing by hand
and today my friend showed me his strategy That he's been perfecting for the last 18 months.
He show me the stats and it was profitable
SO I HAD to see for myself...
I backtested and coded the entire strategy
(feel free to click through the 3 hour video if you're curious to see the behind the scenes)
Mind you this is a strategy...
He's spent 1000s of hours painstakingly back-testing every single trade by hand.
He's gathered 1000s of samples, and the strategy seems profitable
He's even paid a developer to code it up and trades real live capital with it.
The problem with back testing by hand:
- Doesn't accurately account for slippage & commissions
- Data is inaccurate
- Takes too long
And this can lead to having overconfidence in a strategy that in reality is net unprofitable long term.
And I don't do this to S&*T on any particular trader or strategy.
But to save traders DECADES of blindly pursuing a strategy that ultimately loses money.
(and its not just Lewis, its ALL TRADERS)
Which is exactly why I back test all my strategies with code across 20 to 30 years in Tradestation.
- Includes commission & slippage
- 10x more data
- Data is accurate
And in the last few mins of the video I give a quick preview of how I DATAMINE for strategies
So that you don't waste years & $1000s of dollar trading a strategy that has no edge
