Does the Chaikin Money Flow strategy beat buy & hold on Coinbase? (COIN · backtested honestly)
Chaikin Money Flow measures, for each bar, where the close finished inside the bar's high-low range (near the high means buying pressure, near the low means selling pressure), weights that by the bar's volume, and averages it over a lookback window to a reading between -1 and +1. Above zero suggests volume is flowing in ('accumulation'); below zero, out ('distribution'). This rule goes long while the reading is above its zero line and steps aside below - a trend/accumulation reading of volume flow, related to but not the same as On-Balance Volume (which uses close-to-close direction rather than the close's position inside each bar). It lags turns and whipsaws in sideways markets, and a bar with no range or a feed with no volume carries no information - the reading simply steps aside rather than inventing one.
Over this period, Chaikin Money Flow on Coinbase returned +61.3%, while simply buying and holding returned -22.5% — it beat buy & hold by 83.8 points, with a worst drawdown of -63.5%. It traded 54 times and sat in cash about 53% of the time. It's a mechanism you test — not a recommendation.
That's the past — settled, free, and the weakest proof there is. The honest next move isn't to trust it — it's to try to break it: does the edge hold across nearby settings and time, or was it luck? Most strategies that look good here don't survive that, and most should stop there. The few that do still haven't met a future nobody has lived yet. Forward-test Chaikin Money Flow on Coinbase on paper — zero hindsight, losses and all — and get a mechanical alert the day it signals (you trade on your own broker). A hindsight-free track record can only be built by time passing, so the only way to have proof in three months is to start today.
Or stop here — a backtest you can kill for free has already done its job. And if it keeps surviving, that's the rare idea worth trusting with real money.

Beating the dashed line is the whole point — many strategies don't.
- • Max drawdown is the worst peak-to-trough fall you'd have sat through. A higher return with a much deeper drawdown is not obviously better.
- • Every fill assumes next-open execution with costs & slippage on — no acting on prices you couldn't have known.
- • A small number of trades means a small sample. Treat a great-looking result on a handful of trades with suspicion.
This is a hypothetical backtest of a well-known mechanism on past data. It is not advice, not a prediction, and not a claim that the strategy works. I hold no funds and place no orders. The value here is the ability to test an idea honestly — see where it would have helped, and where it would have hurt — before you ever risk real money on your own broker.
