Script update harga saham (indo), reksadana, dan kripto

Saya iseng mengumpulkan beberapa API gratis dari internet untuk menyusun script update harga komoditas di journal hledger saya. Berikut scriptnya, sedottt gan hehe

```bash
#!/bin/bash

kontan_reksadana_cache=$(mktemp)

cleanup() {
        rm -f "$kontan_reksadana_cache"
}
trap cleanup EXIT

ipot_stock_price() {
        today=$(date +"%m/%d/%Y")
        last_week=$(date -d "7 days ago" +"%m/%d/%Y")
        stock_code=$1
        url="https://www.indopremier.com/module/saham/include/json-charting.php?code=$stock_code&start=$last_week&end=$today"
        until close_price=$(curl -s "$url" | jq '.[length -1][4]' 2>/dev/null); do
                sleep 1
        done
        echo "$close_price"
}

kontan_reksadana_price() {
        if ! grep -q "recordsTotal" "$kontan_reksadana_cache"; then
                curl -s -X POST "https://pusatdata.kontan.co.id/reksadana/list/" >"$kontan_reksadana_cache"
        fi
        mf_name=$1
        jq -r ".data[] | select(.[0] == \"$mf_name\")[2]" "$kontan_reksadana_cache"
}

cryptocompare_price() {
        fsym=$1
        tsym=$2
        url="https://min-api.cryptocompare.com/data/price?fsym=$fsym&tsyms=$tsym"
        until price=$(curl -s "$url" | jq -r ".$tsym" 2>/dev/null); do
                sleep 1
        done
        echo "$price"
}

today=$(date +"%Y-%m-%d")

tracked_stocks="BBCA BBNI BMRI"
for stock in $tracked_stocks; do
        price=$(ipot_stock_price "$stock")
        echo P "$today $stock $price IDR"
done

mf_commodity_names=(KISI_FI I_SRILIKUID)
mf_names=(" KISI FIXED INCOME FUND" "Insight Sri Kehati Likuid")
for i in "${!mf_commodity_names[@]}"; do
        price=$(kontan_reksadana_price "${mf_names[$i]}")
        echo P "$today ${mf_commodity_names[$i]} $price IDR"
done

# Assuming USDT is approximately equal to USD
echo P "$today" USDT "$(ipot_stock_price "USD-IDR")" IDR
echo P "$today" BTC "$(cryptocompare_price "BTC" "USD")" USDT
```
