1,215 reliable Awesome Oscillator setups on SPY, 1993-2026.

Beating buy-and-hold on return: 0.

Best made 4.48% a year vs 8.82%.

116,640 backtests on Bollinger vs Keltner vs Casey Bands.

Both decisions on one metric, the share of long variants that made money:

Which band you pick: worth 2.8 percentage points.

Which side you trade: worth 90.4.

On that metric, you are arguing about the wrong variable.

At the default 12/26/9, swapping price for volume beat the plain MACD on profit factor in 3 of 6 markets.

I have run StrategyQuant X since 2019, I earn a commission if you buy it, and my course is built around it.

Saying that first, because the next tweet costs me money.

The $200 line that decides this purchase: 🧵

Checked all of it against the vendor's own pages on 19 Aug 2026.

The review currently outranking mine on "strategyquant x pricing" lists Professional at ~$2,490 and Ultimate at $4,900.

Both wrong. Real: $1,490 and $2,900.

I tested 40 buy-the-dip entries on 33.5 years of SPY. 17,385 trades.

35 of 37 beat drift.

Then I cut the history into three periods. Only 16 held up. 🧵

Two more traps.

Regime filters: 34 entries had one that helped over the whole window. 10 had one that helped in all three periods.

Overlap: DPO and PPO fire on the same days at 0.71. Run both and you hold one trade twice.
