How to add Buy Sell arrows to the plot

[pannet1]

i know this backtesting library uses finplot. can I be able to do similar thing my chart. i am able to all other problems i faced with matplotlib. here is the partial code

    sell_arrow_coords = []
    for i in range(window, len(symbol_data)):
        if ((symbol_data['Close'][i] < top1[i])
                and (symbol_data['Open'][i] > symbol_data['Close'][i])):
            if position is None:
                position = 'short'
                sell_price = symbol_data['Close'][i]
                capital += sell_price * quantity
                buy_arrow_coords.append(
                    (symbol_data.index[i], symbol_data['Low'][i]))
        elif ((symbol_data['Close'][i] > bott1[i])
              and (symbol_data['Open'][i] < symbol_data['Close'][i])):
            if position is None:
                position = 'long'
                buy_price = symbol_data['Close'][i]
                capital -= buy_price * quantity
                sell_arrow_coords.append(
                    (symbol_data.index[i], symbol_data['High'][i]))
        # Close positions if necessary
        if position == "short":
            if (
                (symbol_data['Close'][i] > top2[i])
                and (symbol_data['Open'][i] < symbol_data['Close'][i])
            ):
                position = None
                buy_price = symbol_data['Close'][i]
                capital -= buy_price * quantity
                buy_arrow_coords.append(
                    (symbol_data.index[i], symbol_data['Low'][i])
                )
        elif position == "long":
            if (
                (symbol_data['Close'][i] < bott2[i])
                and (symbol_data['Open'][i] > symbol_data['Close'][i])
            ):
                position = None
                sell_price = symbol_data['Close'][i]
                capital += sell_price * quantity
                sell_arrow_coords.append(
                    (symbol_data.index[i], symbol_data['High'][i]))

    print(f"Final Capital for {symbol}: {capital}")
    ax1 = fplt.create_plot(symbol)
    fplt.plot(top2, legend='UPPER2', ax=ax1)
    fplt.plot(top1, legend='UPPER1', ax=ax1)
    fplt.plot(symbol_data.sma, legend='SMA', ax=ax1)
    fplt.plot(bott1, legend='BOTTOM1', ax=ax1)
    fplt.plot(bott2, legend='BOTTOM2', ax=ax1)
    fplt.candlestick_ochl(symbol_data[['Open', 'Close', 'High', 'Low']])
    fplt.show()

i short, i want to add the buy and sell arrow_coords captured above and plot it on the chart

Of course, the best way to do it is to vectorize your solution. It is much faster and works elegantly with finplot. See example for markers here: https://github.com/highfestiva/finplot/wiki/Examples#featured-example
