Automated Tests for Streaming Chart Service
$30-250 USD
Teslim sırasında ödenir
You need to develop a set of automation tests for the chart streaming service with gRPC interface.
This service does the following:
1. Reads price tick data from data stream
2. Aggregates this data into OHLC Candlesticks
3. Broadcasts the current bar to the streaming server API
4. Stores complete bars into the database
Please use database contents to check if the same candle bar was recieved before a new one has
started.
Note: OHLC (Open High Low Close) Candlestick is a form of prices aggregated in time.
For example, timeframe is 1 minute (1m), so candlebar will be the following:
- Timestamp: Start of the minute, for example 2024-08-01T16:47:00 (note that seconds are
zero)
- Open: price of the very first tick in the timeframe (minute)
- High: maximum price in the timeframe (minute)
- Low: minimum price in the timeframe (minute)
- Close: price of the last tick in the timeframe (minute)
This structure allows to store price history of any number of ticks as 1 integer for the timestamp and
4 floating point numbers for the price.
API Spec:
```grpc
syntax = "proto3";
package [login to view URL];
service ChartService {
rpc Subscribe(SubscribeRequest) returns (stream SubsribeResponse);
}
enum Timeframe {
TIMEFRAME_UNKNOWN = 0;
TIMEFRAME_MINUTE_1 = 1;
}
message SubscribeRequest {
Timeframe timeframe = 1;
repeated string symbol_list = 2;
}
message Candlestick {
uint64 timestamp_msec = 1;
double open = 2;
double high = 3;
double low = 4;
double close = 5;
}
message SubsribeResponse {
string symbol = 1;
Candlestick bar = 2;
}
```
Database DDL:
```sql
CREATE TABLE `candlesticks_m1` (
`symbol` VARCHAR(32) NOT NULL,
`timestamp_msec` BIGINT(20) unsigned NOT NULL,
`open` DECIMAL(24,6) NOT NULL,
`high` DECIMAL(24,6) NOT NULL,
`low` DECIMAL(24,6) NOT NULL,
`close` DECIMAL(24,6) NOT NULL,
PRIMARY KEY (`symbol`,`timestamp`)
);
```
