# Option (indicator) module template

One Python file, same sandbox rules as idea files (numpy/pandas/math only, no files/network, no names starting with `_`).
```python
NAME = "moving_averages"            # lowercase english id: letters, digits, _  (used as opt.<NAME>(df) in idea files)
TITLE = "متوسطات متحركة"             # short Arabic label shown on the site
DESCRIPTION = "EMA/SMA بأطوال مختلفة. المخرجات: ma1, ma2"   # Arabic: what it does + the output keys
PARAMS = {"len1": {"default": 9, "min": 1, "max": 1000, "label": "الطول 1"},
          "kind": {"default": "ema", "choices": ["ema", "sma"], "label": "النوع"}}   # every parameter needs a default (number, string or bool)
OVERLAY = True                      # True = drawn on the price chart (same scale as price); False = separate panel (e.g. RSI, volume)
OUTPUTS = ["ma1"]                   # names of the returned arrays
import numpy as np
import pandas as pd

def compute(df, len1=9, kind="ema"):          # keyword arguments = PARAMS keys, same defaults
    # df columns: time (UTC), open, high, low, close, volume, ticks - closed bars of the chosen timeframe
    # return a dict of 1-D arrays, each the same length as df, CAUSAL (row i uses rows <= i only; no shift(-1), no centered windows)
    ...
    return {"ma1": values}
