TradeLibrary "Trade"
A Trade Tracking Library
Monitor conditions with less code by using Arrays. When your conditions are met in chronologically, a signal is returned and the scanning starts again.
Create trades automatically with Stop Loss, Take Profit and Entry. The trades will automatically track based on the market movement and update when the targets are hit.
Sample Usage
Enter a buy trade when RSI crosses below 70 then crosses above 80 before it crosses 40.
Note: If RSI crosses 40 before 80, No trade will be entered.
rsi = ta.rsi(close, 21)
buyConditions = array.new_bool()
buyConditions.push(ta.crossunder(rsi, 70))
buyConditions.push(ta.crossover(rsi, 80))
buy = Trade.signal(buyConditions, ta.crossunder(rsi, 40))
trade = Trade.new(close-(100*syminfo.mintick), close +(200*syminfo.mintick), condition=buy)
plot(trade.takeprofit, "TP", style=plot.style_circles, linewidth=4, color=color.lime)
alertcondition(trade.tp_hit, "TP Hit")

PositionLibrary "Position"
Allows for simulating trades within an indicator.
newTrade(size, price, timestamp)
Creates a new trade object.
Parameters:
size : The size of the trade (number of shares or contracts).
price : The price at which the trade took place.
timestamp : The timestamp of the trade. Defaults to the current time.
Returns: A new trade object.
start(size, price, timestamp)
Starts a new position.
Parameters:
size : The size of the position (number of shares or contracts).
price : The price at which the position was started.
timestamp : The timestamp of the start of the position. Defaults to the current time.
Returns: A new position object.
trade(pos, size, price, timestamp)
Modifies an existing position.
Parameters:
pos : The position to be modified.
size : The size of the trade (number of shares or contracts).
price : The price at which the trade took place.
timestamp : The timestamp of the trade. Defaults to the current time.
Returns: The modified position object.
exit(pos, price, timestamp)
Closes a position by trading the entire position size at a given price and timestamp.
Parameters:
pos : The position being closed.
price : The price at which the position is being closed.
timestamp : The timestamp of the trade, defaults to the current time.
Returns: The updated position after the trade.
unrealized(pos, price)

GenericTradingLibrary "GenericTrading"
This library aims to collect rare but useful operations for
get_most_recent_long_or_short_position_closed_index() : returns most recent long/short closed bar index.
get_most_recent_long_or_short_position_open_index() : returns most recent long/short closed bar index.
These two functions designed to help to speed up the coding for strategies that contains "re-enter" logic.
These two functions also could applies in the situations where time-count is needed in your condition.
