haveno/apitest/scripts/trade-simulation.sh

#! /bin/bash

# Demonstrates a fiat <-> btc trade using the API CLI with a local regtest bitcoin node.
#
# A country code argument is used to create a country based face to face payment account for the simulated
# trade, and the maker's face to face payment account's currency code is used when creating the offer.
#
# Prerequisites:
#
#  - Linux or OSX with bash, Java 11-15 (JDK language compatibility 11), and bitcoin-core (v0.19 -  v22).
#
#  - Haveno 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:
#    `$ ./haveno-apitest --apiPassword=xyz --supportingApps=bitcoind,seednode,arbdaemon,alicedaemon,bobdaemon --shutdownAfterTests=false`
#
#  - Only regtest btc can be bought or sold with the test payment account.
#
# Usage:
#
#  This script must be run from the root of the project, e.g.:
#
#     `$ apitest/scripts/trade-simulation.sh -d buy -c fr -m 3.00 -a 0.125`
#
#  Script options:  -d <direction> -c <country-code> -m <mkt-price-margin(%)> -f <fixed-price> -a <amount(btc)>
#
# Examples:
#
#    Create and take a buy/eur offer to buy 0.125 btc at a mkt-price-margin of 0%, using an Italy face to face
#    payment account:
#
#       `$ apitest/scripts/trade-simulation.sh -d buy -c it -m 0.00 -a 0.125`
#
#    Create and take a sell/eur offer to sell 0.125 btc at a fixed-price of 38,000 euros, using a France face to face
#    payment account:
#
#       `$ apitest/scripts/trade-simulation.sh -d sell -c fr -f 38000 -a 0.125`
