#! /bin/bash

# Demonstrates a bsq <-> btc swap trade using the API CLI with a local regtest bitcoin node.
#
# Prerequisites:
#
#  - Linux or OSX with bash, Java 11-15 (JDK language compatibility 11), and bitcoin-core (v0.19 -  v22).
#
#  - Bisq must be fully built with apitest dao setup files installed.
#    Build command:  `./gradlew clean build :apitest:installDaoSetup`
#
#  - All supporting nodes must be run locally, in dev/dao/regtest mode:
#           bitcoind, seednode, arbdaemon, alicedaemon, bobdaemon
#
#    These should be run using the apitest harness.  From the root project dir, run:
#    `$ ./bisq-apitest --apiPassword=xyz --supportingApps=bitcoind,seednode,arbdaemon,alicedaemon,bobdaemon --shutdownAfterTests=false`
#
# Usage:
#
#  This script must be run from the root of the project, e.g.:
#
#     `$ apitest/scripts/bsqswap-simulation.sh -d buy -f 0.00005 -a 0.125`
#
#  Script options:  -d <direction> -c <country-code> -f <fixed-price> -a <amount(btc)>
#
# Examples:
#
#    Create and take a bsq swap offer to buy 0.05 btc at a fixed-price of 0.00005 bsq (per 1 btc):
#
#       `$ apitest/scripts/bsqswap-simulation.sh -d buy -a 0.05 -f 0.00005`
#
#    Create and take a bsq swap offer to buy 1 btc at a fixed-price of 0.00005 bsq (per 1 btc):
#
#       `$ apitest/scripts/bsqswap-simulation.sh -d buy -a 1 -f 0.0005`
