We Measured the Support Lines on Our Own Chart. None Worked as Claimed

The short version: many charts draw horizontal "support" lines below the price — pullback levels, round numbers, cancel lines. Our own panel drew them too. So we measured them. Across 32 test cells, not a single level behaved like the support it claimed to be. The one cell that stood out pointed the opposite way.

What we tested

Our chart drew a ladder of eight kinds of levels: three pullback steps, round-number levels above and below price, and a cancel line for short setups. The claim behind each one is simple: when price touches it, it should tend to bounce.

We tested that claim on Bitcoin and Solana, over two time horizons, for all eight levels — 32 cells in total. The data covered 78 weeks of 15-minute futures bars (February 2025 to August 2026, about 52,000 bars per coin).

For each touch, we asked: did price go up more often afterwards than it normally does? We used week-by-week resampling to build honest error bars, and we corrected for the fact that testing 32 things at once produces some lucky-looking results by chance.

What we found

• No level worked as support. After correction, only one cell stood apart from chance: Bitcoin's first pullback level over one hour. But after touching it, price went up 46.8% of the time — less than the normal 50.3%. That is a faint hint of weakness, not support, and even that result was fragile.
• Solana: 16 of 16 cells showed nothing. Not one level carried information.
• Round numbers are not special. We added a control: fake "round" levels, shifted half a step away from the real ones. The fakes did as well as the real round numbers, or better. On Bitcoin's 4-hour horizon, the fakes scored +1.77 against +1.12 for the real ones. On Solana's 1-hour horizon, +1.29 against −1.21.

Why this matters

A line on a chart looks authoritative. It feels like the market "knows" about it. But a level only matters if price behaves differently when it reaches it. Ours did not. The honest reading of a touch is simply: "price reached a place." Nothing more.

We kept the lines on our chart as context — they show where price has been. We removed any wording that called them support.
