# 在OceanOne上挂单买卖任意ERC20 token
2+
![](https://github.com/wenewzhang/mixin_labs-php-bot/raw/master/Bitcoin_php.jpg)
3+
4+
在[上一课](https://github.com/wenewzhang/mixin_labs-java-bot/blob/master/README5.md)中，我们介绍了如何在OceanOne交易比特币。OceanOne支持交易任何Mixin Network上的token，包括所有的ERC20和EOS token，不需要任何手续和费用，直接挂单即可。下面介绍如何将将一个ERC20 token挂上OceanOne交易！
5+
6+
此处我们用一个叫做Benz的[ERC20 token](https://etherscan.io/token/0xc409b5696c5f9612e194a582e14c8cd41ecdbc67)为例。这个token已经被充值进Mixin Network，你可以在[区块链浏览器](https://mixin.one/snapshots/2b9c216c-ef60-398d-a42a-eba1b298581d )看到这个token在Mixin Network内部的总数和交易
7+
### 预备知识:
8+
先将Ben币存入你的钱包，然后使用**getAssets** API读取它的UUID.
9+
10+
### 取得该币的UUID
11+
调用 **getAssets** API 会返回json数据, 如:
12+
13+
- **asset_id** 币的UUID.
14+
- **public_key** 该币的当前钱包的地址.
15+
- **symbol** 币的名称. 如: Benz.
16+
17+
```php
18+
if ($line == 'aw') {
19+
$mixinSdk_eachAccountInstance = GenerateWalletSDKFromCSV();
20+
$asset_info = $mixinSdk_eachAccountInstance->Wallet()->readAssets();
21+
foreach ($asset_info as $key => $asset) {
22+
echo $asset["symbol"] . " " . $asset["asset_id"] ." ". $asset["balance"] .
23+
" ". $asset["public_key"].PHP_EOL;
24+
}
25+
}
26+
```
27+
调用 **getAssets** API的完整输出如下:
28+
```bash
29+
Make your choose:aw
30+
run...
31+
client id is:26b20aa5-40c0-3e00-9de0-666cfb6f2daa

37+
```
38+
### 限价挂单
39+
- **挂限价买单** 低于或者等于市场价的单.
40+
- **挂限价卖单** 高于或者是等于市场价的单.
41+
42+
OceanOne支持三种基类价格: USDT, XIN, BTC, 即: Benz/USDT, Benz/XIN, Benz/BTC, 这儿示范Benz/USDT.
43+
44+
### 限价挂卖单.
45+
新币挂单后,需要等一分钟左右，等OceanOne来初始化新币的相关数据.
46+
47+
```php
48+
if ( $ocmd == 's1') {
49+
$p = readline("Input the Price of XIN/USDT: ");
50+
$a = readline("Input the Amount of XIN: ");
51+
$tMemo = GenerateOrderMemo("A",USDT_ASSET_ID,$p);
52+
echo $tMemo . PHP_EOL;
53+
$mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
54+
$asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(XIN_ASSET_ID);
55+
print_r($asset_info);
56+
if ( (float) $asset_info["balance"] >= (float) $a ) {
57+
$transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(XIN_ASSET_ID,OCEANONE_BOT,
58+
$mixinSdk_WalletInstance->getConfig()['default']['pin'],
59+
$a,
60+
$tMemo);
61+
print_r($transInfos);
62+
echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL;
63+
} else { echo "Not enough XIN!\n";}
64+
}
65+
```
66+
67+
### 限价挂买单.
68+
新币挂单后,需要等一分钟左右，等OceanOne来初始化新币的相关数据.
69+
70+
```php
71+
if ( $ocmd == 'b1') {
72+
$p = readline("Input the Price of XIN/USDT: ");
73+
$a = readline("Input the Amount of USDT: ");
74+
$tMemo = GenerateOrderMemo("B",XIN_ASSET_ID,$p);
75+
echo $tMemo . PHP_EOL;
76+
$mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
77+
$asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(USDT_ASSET_ID);
78+
79+
print_r($asset_info);
80+
if ( ((float) $asset_info["balance"] >= 1) && ( (float) $asset_info["balance"] >= (float) $a ) ) {
81+
$transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(USDT_ASSET_ID,OCEANONE_BOT,
82+
$mixinSdk_WalletInstance->getConfig()['default']['pin'],
83+
$a,
84+
$tMemo);
85+
print_r($transInfos);
86+
echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL;
87+
} else { echo "Not enough USDT!\n";}
88+
}
89+
```
90+
### 读取币的价格列表
91+
读取币的价格列表，来确认挂单是否成功!
92+
93+
```php
94+
if ( $ocmd == '2') { getOceanOneMarketInfos(ERC20_BENZ,USDT_ASSET_ID);}
95+
function getOceanOneMarketInfos($targetCoin, $baseCoin) {
96+
$client = new GuzzleHttp\Client();
97+
$baseUrl = "https://events.ocean.one/markets/".$targetCoin."-".$baseCoin."/book";
98+
$res = $client->request('GET', $baseUrl, [
99+
]);
100+
if ($res->getStatusCode() == "200") {
101+
// echo $res->getStatusCode() . PHP_EOL;
102+
$resInfo = json_decode($res->getBody(), true);
103+
echo "Side | Price | Amount | Funds" . PHP_EOL;
104+
foreach ($resInfo["data"]["data"]["asks"] as $key => $exchange) {
105+
echo $exchange["side"] . " " . $exchange["price"] . " " . $exchange["amount"] ." " . $exchange["funds"] . PHP_EOL;
106+
}
107+
foreach ($resInfo["data"]["data"]["bids"] as $key => $exchange) {
108+
echo $exchange["side"] . " " . $exchange["price"] . " " . $exchange["amount"] ." " . $exchange["funds"] . PHP_EOL;
109+
}
110+
}
111+
}
112+
```

4+
OceanOne is introduced in [last chapter](https://github.com/wenewzhang/mixin_labs-php-bot/blob/master/README5.md), you can trade Bitcoin. All kinds of crypto asset on Mixin Network can be listed on OceanOne.All ERC20 token and EOS token can be listed. Following example will show you how to list a ERC20 token.
5+
6+
There is a [ERC20 token](https://etherscan.io/token/0xc409b5696c5f9612e194a582e14c8cd41ecdbc67) called Benz. It is deposited into Mixin Network. You can search all transaction history from [Mixin Network browser](https://mixin.one/snapshots/2b9c216c-ef60-398d-a42a-eba1b298581d )

### Pre-request:
9+
Deposit some coin to your wallet, and then use **getAssets** API fetch the asset UUID which Mixin Network gave it.
10+
11+
### Get the ERC-20 compliant coin UUID
12+
The **getAssets** API return json data, for example:
13+
14+
- **asset_id** UUID of this coin
15+
- **public_key** The wallet address for this coin
16+
- **symbol** Coin name, Eg: Benz.
17+
18+
```php
19+
if ($line == 'aw') {
20+
$mixinSdk_eachAccountInstance = GenerateWalletSDKFromCSV();
21+
$asset_info = $mixinSdk_eachAccountInstance->Wallet()->readAssets();
22+
foreach ($asset_info as $key => $asset) {
23+
echo $asset["symbol"] . " " . $asset["asset_id"] ." ". $asset["balance"] .
24+
" ". $asset["public_key"].PHP_EOL;
25+
}
26+
}

- **Limit Order to Buy** at or below the market.
41+
- **Limit Order to Sell** at or above the market.
42+
43+
OceanOne support three base coin: USDT, XIN, BTC, that mean you can sell or buy it between USDT, XIN, BTC, so, you have there order: Benz/USDT, Benz/XIN, Benz/BTC, here show you how to make the sell order with USDT.
44+
45+
### Make the limit order to sell.
46+
47+
```php
48+
if ( $ocmd == 's1') {
49+
$p = readline("Input the Price of XIN/USDT: ");
50+
$a = readline("Input the Amount of XIN: ");
51+
$tMemo = GenerateOrderMemo("A",USDT_ASSET_ID,$p);
52+
echo $tMemo . PHP_EOL;
53+
$mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
54+
$asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(XIN_ASSET_ID);
55+
print_r($asset_info);
56+
if ( (float) $asset_info["balance"] >= (float) $a ) {
57+
$transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(XIN_ASSET_ID,OCEANONE_BOT,
58+
$mixinSdk_WalletInstance->getConfig()['default']['pin'],
59+
$a,
60+
$tMemo);
61+
print_r($transInfos);
62+
echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL;
63+
} else { echo "Not enough XIN!\n";}
64+
}
65+
```
66+
67+
### Make the limit order to buy.
68+
After the order commit, wait 1 minute to let the OceanOne exchange initialize it.
69+
```php
70+
if ( $ocmd == 'b1') {
71+
$p = readline("Input the Price of XIN/USDT: ");
72+
$a = readline("Input the Amount of USDT: ");
73+
$tMemo = GenerateOrderMemo("B",XIN_ASSET_ID,$p);
74+
echo $tMemo . PHP_EOL;
75+
$mixinSdk_WalletInstance = GenerateWalletSDKFromCSV();
76+
$asset_info = $mixinSdk_WalletInstance->Wallet()->readAsset(USDT_ASSET_ID);
77+
78+
print_r($asset_info);
79+
if ( ((float) $asset_info["balance"] >= 1) && ( (float) $asset_info["balance"] >= (float) $a ) ) {
80+
$transInfos = $mixinSdk_WalletInstance->Wallet()->transfer(USDT_ASSET_ID,OCEANONE_BOT,
81+
$mixinSdk_WalletInstance->getConfig()['default']['pin'],
82+
$a,
83+
$tMemo);
84+
print_r($transInfos);
85+
echo "The Order ID (trace_id) is: " . $transInfos["trace_id"] . PHP_EOL;
86+
} else { echo "Not enough USDT!\n";}
87+
