DcaPal is a pragmatic Dollar Cost Averaging tool for passive investors like me: financially-educated people managing their own portfolios of not-too-many assets replicating major world indices.

I was facing a common problem: it's that time of the month, got some savings to invest and have to split them across my portfolio assets. How the heck can I do it so that my portfolio stays balanced?

Hence DcaPal. You come here every week/month/quarter, build your portfolio, define asset allocation in percentage, input how much you want to invest and let the algorithm do the splitting for you.

You can start using DcaPal right away. It's free. No registration required.

Build your own portfolio or, if you don't know where to start, explore our Demo portfolios:

• 60/40 Portfolio
• All-seasons Portfolio
• 21Shares Crypto Basket 10 (HODLX)

DcaPal does not store any user data. But if you are still concerned for your privacy, you can build and run it on your machine.

Start Docker environment

• Setup the .env file

cp dcapal-backend/.env.example dcapal-backend/.env

• Setup a password for the db and the JWT secret (you can use openssl rand -base64 32 to generate a random string) in the new .env file

POSTGRES_PASSWORD=<replace-with-your-pwd>
JWT_SECRET=<generated_secret>

• Start the Docker environment

make dev-up

(Note: if you're using a Mac with an ARM processor, you should replace (in the docker-compose dev file) Cadvisor's image version with gcr.io/cadvisor/cadvisor:v0.47.1 and set platform: linux/aarch64)

Run DcaPal backend

Prepare dcapal.yml config file

cd dcapal-backend
cp config/dcapal/dcapal.yml dcapal.yml

Compile and start backend service

cargo run --release

Run DcaPal frontend

Build DcaPal Optimizer

cd dcapal-optimizer-wasm
curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
wasm-pack build --release
