Smart Accumulator on Kraken

Smart Accumulator buys a coin on a schedule and holds it, like dollar-cost averaging, but sizes each buy by price. It compares the last daily close with the coin's 200-day average: below the average it buys 1.5x the amount, more than 1.5x above it it buys half, otherwise the normal amount. The default is $100 every Monday (UTC), and everything is a setting: the amount, daily, weekly or monthly buys, the multipliers and a total spending cap. An optional take-profit sells 10% of the holding when price is more than twice its 200-day average, at most once every 30 days. Spot only: no leverage, no shorts, no stop-loss. It cannot make money on a coin that keeps falling: buying more below the average means holding more of it. Tested on 43 coins with settings fixed before the test: the smart rule bought at a lower average price than plain weekly buying in 98% of cases. Over 2 years BTC returned a median 38% on the money put in. On 20 altcoins it was never tuned on, in a mostly falling market, the median 2-year result was -14% (plain weekly buying -18%), and about break-even with the take-profit on.
