Library "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")

Nota Keluaran

v2 Added Stop and Limit orders.

Now you can track stop and limit orders. If you place a new trade with custom entry that is not the current market price, the trade will remain inactive until the market prices cross your entry point. Targets will not be tracked until we cross the threshold.

See these 2 examples of a buy limit. The green background activate when the trade is active.

v3

New property `profit`

Now you can check your trade profit by referencing the profit property. A negative value means that is a loss.

Example

// import DevLucem/Trade/3 as Trade
trade = Trade.new(close-(100*syminfo.mintick), close +(200*syminfo.mintick), close, condition=buy_condition)
plot(trade.profit)

Updated:
Trade
  Fields:
    stoploss (series float)
    takeprofit (series float)
    entry (series float)
    active (series bool)
    sl_hit (series bool)
    tp_hit (series bool)
    open (series int)
    profit (series float)

v7

Updated:
method signal(conditions, reset_conditions, reset)
  Signal Conditions
  Namespace types: array<bool>
  Parameters:
    conditions (array<bool>)
    reset_conditions (array<bool>)
    reset (bool)
  Returns: Array [Signal, State]: True when all the conditions have occured


Now you can see the state of your scanning. Also send a list of reset conditions that allow you to reset the scanning state.

Example usage:

rsi = ta.rsi(close, 14)
ema = ta.ema(close, 14)
[buy, state] = signal(
 
 // Enter a trade when rsi goes below 20 then price crosses below 5 EMA and finally rsi crosses above 20
 array.from(ta.crossunder(rsi, 20), ta.crossunder(close, ema), ta.crossover(rsi, 20)), 
 
 // Make sure rsi doesnt cross 80 after crossing 20 then rsi doesn't cross below 20 after crossing the EMA and anything can happen afterwards.
 array.new_bool(0, false)
 // array.from(ta.crossunder(rsi, 80), ta.crossunder(rsi, 20), false)
 )

trade = new(high + (50*syminfo.mintick), close -(200*syminfo.mintick),buy[1], close, update=false)
bgcolor(color.new(color.red, 100 - (state*15)))

plotshape(buy and na(trade.entry[1]), "Sell", shape.labeldown, location.abovebar, color.red, 0, "SELL", color.white)
start = plot(trade.entry, "Entry", style=plot.style_circles, linewidth=2, color=color.aqua)
toSL = plot(trade.stoploss, "SL", style=plot.style_circles, linewidth=1, color=color.red)
toTP = plot(trade.takeprofit, "TP", style=plot.style_circles, linewidth=1, color=color.lime)
fill(start, toTP, color.new(color.lime, 80))
fill(start, toSL, color.new(color.red, 80))
