Indeed, plot triangle size is proportional to trade size:

def _plot_pl_section():
"""Profit/Loss markers section"""
fig = new_indicator_figure(y_axis_label="Profit / Loss")
fig.add_layout(Span(location=0, dimension='width', line_color='#666666',
line_dash='dashed', line_width=1))
returns_long = np.where(trades['Size'] > 0, trades['ReturnPct'], np.nan)
returns_short = np.where(trades['Size'] < 0, trades['ReturnPct'], np.nan)
size = trades['Size'].abs()
size = np.interp(size, (size.min(), size.max()), (8, 20))
trade_source.add(returns_long, 'returns_long')
trade_source.add(returns_short, 'returns_short')
trade_source.add(size, 'marker_size')
