Stealth StopLosses?

Simple, not any dif than a real path
just use rules to close a transaction, rather than transfer a sl

heres a couple of lines of code only for you, u want have orders chosen

Inserted Code if (! HideTakeProfitOrderType()==OP_SELLOrderTakeProfit( )! =OrderOpenPrice()-TakeProfit*my_point) OrderModify(OrderTicket(),OrderOpenPrice(),OrderOp enPrice()-TakeProfit*my_point,OrderTakeProfit(),0,CLR_NONE); if (! HideTakeProfitOrderType()==OP_BUYOrderTakeProfit() ! =OrderOpenPrice() TakeProfit*my_point) OrderModify(OrderTicket(),OrderOpenPrice(),OrderOp enPrice() TakeProfit*my_point,OrderTakeProfit(),0,CLR_NONE); if (HideTakeProfitOrderType()==OP_SELLMarketInfo(Orde rSymbol(),MODE_BID)lt;=OrderOpenPrice()-TakeProfit*my_point) OrderClose(OrderTicket(),OrderLots(),MarketInfo(Or derSymbol(),MODE_BID),Slippage,CLR_NONE); if (HideTakeProfitOrderType()==OP_BUYMarketInfo(Order Symbol(),MODE_ASK)gt;=OrderOpenPrice() TakeProfit*my_point) OrderClose(OrderTicket(),OrderLots(),MarketInfo(Or derSymbol(),MODE_ASK),Slippage,CLR_NONE);

Best way to set up globals for multi would be to use special identifiers:

AccountNumber_TradeTicket_[StopLoss]
23875443_19283_[60]

Then its simple to parse it using the stringsearch and conversion purposes. After that its simple to make works CreateGlobalStop() and GetGlobalStop()

Factors work for a single commerce, hard to apply to multiple.

It seems like I will have to write to a file a log of ticks. (to exchange management of SL)

Use GlobalVariables for the StopLoss, Current Trailing Stop, Etc.. - They dont expire after use for 4 months. Http://book.mql4.com/variables/globals - Of course your PC needs to be on and running however, the PC can be restarted and you pick up where you left off.

You cant.

Should you dont have some connection to a broker (plus they dont understand where you want your SL - monitoring or otherwise) then no SL will exist.

Best fit would be to code your monitoring SL logic into your 'EA' in a recoverable manner, and monitor if your EA is still attached. If not then it ought to warn you (by SMS / email etc)

A recoverable manner ....

Shop all transaction information in arrays (or structures if language aside from MQL)

E.G. unique Magic, available price, kind (buy/Sell), H/L price, pip count, SL size, SL price etc and save all these arrays at regular intervals to a file.

You'll also have to code patterns to load these values on EA initialisation - in cases where your EA/PC crashes.

And patterns to 'understand' when you have returned from a temporary connection a crash so you can examine the current state of play verses the previous period before the outage.

I would advise you set a fixed SL together with the broker that is further from price compared to actual stealth cease but not so far as to be non existant

IE if your Stealth stop is currently 30 pips from price then set a broker cease 100 pips off so That You have some astrophe coverage

I understand how to code a standard stealth stoploss. That's not difficult in any way.

Imagine if I needed to put in a trailing stop? How can I make that stealth and still maintain recoverability if the EA shuts down, power outage, system reset etc.. Further, how can I place that so it works for multiple orders?
