ttools
A Python library for tools, utilities, and helpers for my trading research workflow.
Modules:
utils
vbtutils
Contains helpers for vbtpro
AnchoredIndicator - allows runing any vbt indicator in anchored mode (reset by Day, Hour etc.)
Example usage:
from ttools import AnchoredIndicator
mom = vbt.indicator("talib:MOM").run(t1data.data["BAC"].close, timeperiod=10, skipna=True) #standard indicator
mom_anch_d = AnchoredIndicator("talib:MOM", anchor='D').run(t1data.data["BAC"].close, timeperiod=10, skipna=True) #anchored to D
create_mask_from_window - creates mask of the same size AS INPUT, True values denotes that the window is open. Used to filter entry window or forced eod window. Range is denoted by pair (start, end) indicating minutes elapsed from the market start of that day.
from ttools import create_mask_from_window
entry_window_opens = 3 #in minutes from start of the market
entry_window_closes = 388
forced_exit_start = 387
forced_exit_end = 390
#create mask based on main session that day
entry_window_opened = create_mask_from_window(entries, entry_window_opens, entry_window_closes)
#limit entries to the window
entries = entries & entry_window_opened
#create forced exits mask
forced_exits_window = create_mask_from_window(exits, forced_exit_start, forced_exit_end)
#add forced_exits to exits
exits = exits | forced_exits_window
exits.tail(20)
isrising(series,n),isfalling(series, n) - returns mask where the condition is satisfied of consecutive rising or falling elements
Indicators
Custom indicators in the indicators folder.
Importing
from ttools.vbtindicators import register_custom_inds
register_custom_inds(None, "override") #All indicators from the folder are automatically imported and registered.
register_custom_inds("CUVWAP", "override")#just one
After registration they can be listed and used
vbt.IF.list_indicators("ttools")
vbt.phelp(vbt.indicator("ttools:CUVWAP").run)
vwap_cum_d = vbt.indicator("ttools:CUVWAP").run(s12_data.high, s12_data.low, s12_data.close, s12_data.volume, anchor=vbt.Default(value="D"), drag=vbt.Default(value=50), hide_default=True)
Creating
To create custom indicators CUSTOMNAME.py in indicators folder is created containing varibles IND_CUSTOMNAME containing the Indicator Factory class.
Available
CUVWAP- Cumulative VWAP with anchor based on HLCC4 with optional rounding (hlcc4_round, def.3) and drag - warming period from previous anchor unit(def.0).DIVERGENCE- Various divergences between two timeseries (abs, relative, relative normalized, pct, abs pct)
