I know how to code a standard, plain vanilla stealth stoploss. That's not difficult at all.

What if I wanted 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 set that so it works for multiple orders?

You cant.

If you dont have any connection to your broker (and they dont know where you want your SL - trailing or otherwise) then no SL will exist.

Best fit is to code your own trailing SL logic into your 'EA' in a recoverable manner, and monitor if your EA is still connected. If not then it should warn you (by SMS / email etc)

A recoverable manner ....

Store all trade info in arrays (or structures if language other than MQL)

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

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

And routines to 'know' when you've returned from either a temporary connection outage or a crash so you can examine the current state of play verses the the last period before the outage.

I'd advise you set a fixed SL with the broker that is further from price than your real stealth stop but not so far as to be non existant

IE if your Stealth stop is currently 30 pips from price then set a broker stop 100 pips away so you have some disaster coverage

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

Global variables work for one trade, hard to apply to multiple.

It looks like I'll have to write to a file a log of ticks. (to trade direction of SL)

Best way to setup globals for multi is to use unique identifiers:

AccountNumber_TradeTicket_[StopLoss]
23875443_19283_[60]

Then its easy to parse it using the stringsearch and conversion functions. After that its easy to create functions CreateGlobalStop() and GetGlobalStop()

simple, not any dif than a real trail
just use rules to close a trade, instead of move a sl

heres a few lines of code just for you, u need have orders selected

Inserted Code

    if (!HideTakeProfit&&OrderType()==OP_SELL&&OrderTakeProfit()!=OrderOpenPrice()-TakeProfit*my_point)  
    {
    OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice()-TakeProfit*my_point,OrderTakeProfit(),0,CLR_NONE);
    }
    if (!HideTakeProfit&&OrderType()==OP_BUY&&OrderTakeProfit()!=OrderOpenPrice()+TakeProfit*my_point)   
    {
    OrderModify(OrderTicket(),OrderOpenPrice(),OrderOpenPrice()+TakeProfit*my_point,OrderTakeProfit(),0,CLR_NONE);
    }
    
    if (HideTakeProfit&&OrderType()==OP_SELL&&MarketInfo(OrderSymbol(),MODE_BID)<=OrderOpenPrice()-TakeProfit*my_point)  
    {
    OrderClose(OrderTicket(),OrderLots(),MarketInfo(OrderSymbol(),MODE_BID),Slippage,CLR_NONE);
    }
    if (HideTakeProfit&&OrderType()==OP_BUY&&MarketInfo(OrderSymbol(),MODE_ASK)>=OrderOpenPrice()+TakeProfit*my_point)   
    {
    OrderClose(OrderTicket(),OrderLots(),MarketInfo(OrderSymbol(),MODE_ASK),Slippage,CLR_NONE);
    }

RR a better idea just hit me. Just add 1000 pips to your SL/TP and save it right in the order as normal. Simpy have your stealth exit routine subtract 1000 pips from the in-order SL or TP. Makes it easy to save and easy to read.

Sounds like a good idea, storing the real TP/SL inside a big TP/SL.

Hi everyone.

First off, these are very brilliant solutions I see here. The main problem I'm having with my versions of these codes is recoverability.

Let's say the trailing stop is 40 pips.
The current stoploss distance is 30 pips.
Suddenly, the terminal shuts down.
During that period:

Price moves up 70 pips
Retraces 30 pips.

When the terminal comes back online, the stoploss--according to the trailing stop--should be the current price - 10 pips. But, to the EA, the price moved 40 pips up, which pulls the stoploss up to 40 pips below the current price instead of 10.

Any solution for that? I was thinking of using the high/low of a bar. The problem is I can't always tell if the high/low happened after the trade.

Start with the OrderOpenTime() and iBarshift on M1 till the Current time. extract the high M1 value from each bar and save the highest to compute the highest pip profit. Its a little messy but it works but it kinda doesnt matter for your example because you missed the high and if you're 30 pips underwater the Trailer would have activated. You just have to play it from your restore point.

Just trail the high/low of 1 min candles between order open and current time. If 1 min candles are not enough then there really is no good solution and you will probably have to find another broker (other platform probably) that allowes server side stops.

We can trace the Highest/Lowest price within a range of bars easily using iHighest() & iLowest()

The issue is what happens if the trade is placed on the same bar. (presumably after the high).

I realize this isn't perfect, but at least I'm trying to cover my bases.
