Average Account Balance

The following code gets the average balance of an account over 25 periods with an interval of blockInterval blocks, ending at block endBlock (but counting back from that block).

Code

let total = constant(0);
const periods = 25;
for (let i = 0; i < periods; i++) {
    const targetBlock = sub(endBlock, mul(constant(i), blockInterval));
    const bal = getAccount(targetBlock, user).balance().toCircuitValue();
    total = add(total, bal);
}
const avg = div(total, constant(periods));
addToCallback(avg);

Inputs

{
    "user": "0xe76a90E3069c9d86e666DcC687e76fcecf4429cF",
    "endBlock": 9900000,
    "blockInterval": 1000
}
