# Market Data Form Finder Toolkit (MDFFT)

The project goal is to make working with a raw market data easier. Provide a tool that allow to identify recurrent market patterns.
Any types of market can processed by this.

The library allow to carry out following tasks:
* Load a list of quotes for any instrument.
* Create a chart using the Japanese candlestick format.
* Draw lines and markers on the chart.
* Search for candles using various criteria.
* Navigate through the entire candles collection.
* Change the timeframe to different one.

<a id="install"></a>
## Install ##

```bash
 pip install mdfft
```

<a id="import_classes"></a>
## Import classes

The namespace **mdfft** contains of whole list of lib's classes. The example of import is below:

```python
from mdfft import Candles, SimpleParser, Styler, painter as p, RawCandle, Trader
```

Classes:
* Candle - The class represents a Japanese candle
* Candles - The class represents a Japanese candle list
* RawCandle - The simple class that based to create Candle. May used in quote parsers.
* painter - The object to draw a chart.
* Style - The class to appearance a chart.
* SimpleParser - The class to parse candles for my samples.

## Candle collection examples ##

<a id="cc_load"></a>
### Load candles ###

The collection of candles is created by parsing quotes or making an array of RawCandle objects. The array of RawCandles is created by the programmer himself.

```python
   raw_candles = [
        RawCandle(
            dt=datetime(2020, 1, 1), # Candle datetime
            o=2,                     # Open price
            h=4,                     # High price
            l=1,                     # Low price
            c=3                      # Close price
        ),
        RawCandle(
            dt=datetime(2020, 1, 2), # dt
            o=12,                    # ohlc prices
            h=14,
            l=11,
            c=13
        )
    ]
    candles = Candles.from_raw_candles(raw_candles, timeframe="1D")
    print(candles)
```

Next I will use my SimpleParser and my rather large data set of OHLC quotes.

```python
 parser = SimpleParser(file="./data/EURUSD_H1.txt")
 candles = Candles.from_raw_candles(parser.parse(), timeframe="1H")
```

<a id="cc_count"></a>
#### Count of candles in the dataset

```python
    print(candles.candles_count())
    print(len(candles))
```

<a id="cc_first_and_last"></a>
#### A first and a last candle in the dataset

```python
    start_candle = candles.head()
    print("Start candle: " + str(start_candle))

    end_candle = candles.tail()
    print("End candle: " + str(end_candle))
```

<a id="cc_get_candle_by_index"></a>
#### Get a candle by an index

```python
    my_candle = candles.candle_at(1985)
    same_candle = candles[1985]
```

<a id="cc_navigation"></a>
#### Navigation through a dataset

Navigation is performed by calling ``next()`` and ```prev()``` methods of a candle object.

```python
    next_candle = my_candle.next()
    prev_candle = my_candle.prev()
    next20_candle = my_candle.next(20)
    prev30_candle = my_candle.prev(30)
```

<a id="cc_search_by_date"></a>
#### Search by a date

```python
    found_candle = candles.find_candle(datetime(1999, 1, 4, 5))
    if not found_candle:
        print("Candle not found at 1999-01-04 05:00")
    return print("Found candle: " + str(found_candle))
```

<a id="cc_sub_collection_by_index"></a>
#### Get a subcollection from the main collection by indices

```python
    # take 10 skip 5 candles
    print(candles.take(10, skip=5))
    # or  print(candles[5:15])

    # skip 5 candles from collection
    print(candles.skip(5))
    # or  print(candles[5:])
```

<a id="cc_sub_collection_by_date"></a>
#### Get a subcollection from the main collection by dates

```python
    from datetime import datetime
    # New candles collection from 2000-01-01 to 2000-01-10
    # Note Only if candles are exists
    candles_range = candles.range_dt( datetime(2000, 1, 3,  1 ), datetime(2000, 1, 10, 1))
    if not candles_range:
        print("No candles in range")
        return 0
    print("Count candles: " + str(candles_range.candles_count()))
    print(candles_range)
```

<a id="cc_iteration"></a>
#### Iterate over a collection ####

```python
    # Iterate candles
    for candle in candles:
        print("Candle: " + str(candle))
```

<a id="cc_high_and_low"></a>
#### A highest and a lowest candle in the collection

```python
    # Get the high candle and the low candle
    candle_h, candle_l = candles.high_and_low_candles()
    print("High candle: " + str(candle_h))
    print("Low candle: " + str(candle_l))
```

<a id="tf"></a>
### Timeframes

A candle collection may be converted from a current timeframe to another timeframe. A new timeframe must be bigger than the source timeframe.

Example: the timeframe of 1 hour **may be** converted to 2 hours, 8 hours, 2 days, or another one, but bigger than source one.
The 1 hour timeframe **must not** convert to 45 minutes, 30 minutes, or another one less.

A timeframe label consists of two parts: a number of time units and a time unit label.

Example of timeframes: _24M_ - 24 minutes timeframe, _1H_ - 1 hour timeframe, _11H_ - 11 hours timeframe, _1D_ - 1 day timeframe, _11D_ - 11 days timeframe

Possible time unit labels:
* **M** - minute
* **H** - hour
* **D** - day
* **W** - week
* **MONTH** - month

<a id="tf_current"></a>
#### Get a timeframe of a candles collection

```python
    print(candles.timeframe)
```

<a id="tf_change"></a>
#### Change a candles collection timeframe

```python
    candles_2h  = candles.to_tf("2H")
    candles_3h  = candles_2h.to_tf("3H")
    candles_4h  = candles_3h.to_tf("4H")
    candles_13h = candles_4h.to_tf("13H")
    candles_1d  = candles_4h.to_tf("1D")
```

<a id="pd"></a>
### Pandas

Convert a candles collection to a pandas dataframe

```python
    from mdfft import PandasCandles

    df = PandasCandles.candles_to_pandas_df(candles)
    print(df)
```

You may create a dataset in which a row contains several candles prices.

```python
    from mdfft import PandasCandles

    # 3 candles in a single row
    df_windows = PandasCandles.candles_windows_to_pandas_df(candles, 3)
    print(df_windows)
```

    candle = candles.candle_at(1985)

    # Next candle
    next_candle = candle.next()

    # 30 candles to forward
    next30_candle = candle.next(30)

    # Prev candle
    prve_candle = candle.prev()

    # Prev 100 candle
    prev100_candle = candle.prev(100)
```

<a id="c_type"></a>

    # Candle index from back
    cib = candle.index_back # or candle.ib or candle['ib']
```

<a id="ct"></a>
### Candle chart

To start painting you **must** import bellow classes

```python
    from mdfft import painter as p, Styler
```

Matplotlib is used for drawing. That means you may use colors, marker, visual elements, etc. from Matplotlib.


<a id="ct_simple"></a>
#### Simple chart

```python
    p.start_paint()
    p.title="Candles"
    p.paint(candles_collection)
    p.paint_done()
```

<a id="ct_save"></a>
#### Save chart to file

```python
    p.start_paint()
    p.title = "Save paint"
    p.paint(candles_to_paint)
    p.save_paint('candles.jpg')
```

<a id="ct_tune"></a>
#### Appearance

The appearance is performed through the object of class Styler that included in object painter. Possible settings is an enum in class Styler.

```python
    # The appearance of the chart is configured through the object Styler
    # Each candle has own the color of body, shadow and border
    s = Styler()
    p.title="Rainbow candles"
    s.color_bear_body =   [plt.cm.get_cmap('Pastel1', candles_cnt)(c) for c in range(candles_cnt)]
    s.color_bear_border = [plt.cm.get_cmap('Set1_r',  candles_cnt)(c) for c in range(candles_cnt)]
    s.color_bear_shadow = "blue"
    s.color_bull_body =   [plt.cm.get_cmap('turbo',   candles_cnt)(c) for c in range(candles_cnt)]
    s.color_bull_border = [plt.cm.get_cmap('tab20b',  candles_cnt)(c) for c in range(candles_cnt)]
    s.color_bull_shadow = "green"

    # Apply style
    p.styler = s

    # Draw candles
    p.start_paint()
    p.paint(candles)
    p.paint_done()
```

<a id="ct_draw_on_chart"></a>
#### Drawing on the chart

Possible markers and lines

```python
    p.start_paint()

    # Paint candles
    p.paint(candles_to_paint)

    # Paint markers for each 5 candles
    for c in candles_to_paint:
        if (c.index % 5) == 0:
            p.paint_marker(c, "l", marker_size=4, marker_color='red', marker='v')
            p.paint_marker(c, "h", marker_size=3, marker_color='black', marker='^')
            p.paint_marker(c, c.mid, marker='_')

    # Paint line. From hightest price to lowest price
    hc, lc = candles_to_paint.high_and_low_candles()
    p.paint_line( hc, hc.high, lc, lc.low, line_style="dotted", line_color="green")

    # Show picture
    p.paint_done()
```

<a id="t"></a>
### Trading

For the success or failure of a position, the Trader class is used. The class contains a single method that returns the result of a position at a certain point.

```python
    pip = 1 / 10000
    start_candle = candles.candle_at(12345)
    trader = Trader()

    profit, distance, action_price = trader.place_order(
        candle=start_candle,              # candle for order, not datetime
        order_price='o',                  # open price - possible 'o' 'h' 'l' 'c' OR float
        place_type=Trader.PLACE_TYPE_BUY, # PLACE_TYPE_BUY or PLACE_TYPE_SELL
        sl=start_candle.low - pip,        # stop loss
        tp=start_candle.high + pip * 100, # take profit
        tl=1000                           # candles before force close. time to live position
    )

    # My profit. Positive or negative
    print(f"Profit pips: {profit / pip}")

    # Candles from start before close order
    print(f"Candles to close order: {distance}")

    # Price that close order
    print(f"Price that close order: {action_price}")
```
