Question about EA programming...

  • First Post: Aug 18, 2009 2:17am Aug 18, 2009 2:17am
Hi, there is something i need to ask,
Someone ask me to make an EA with this as one of the feature:

1)Stealth Mode: System needs to have a stealth mode.
a)The stealth mode is designed to hide the real stop loss and target profit.
So if stealth mode is true, then EA should send a stop loss of random figures between 150 to 320 pips with the entry order made visible to broker to see
If stealth mode is true, then EA should send A profit target of random figures between 150 to 320 pip with the entry order made visible to broker to see
These stops loss and Take profit target price are known as the broker stops and broker take profit, these are to be made visible to the broker during entry order..
b)EA needs to have input settings for user to enter their actual real stop loss and real profit target. The real stop loss and real take profit are known as stealth mode and these figures are to be managed by the EA and should NOT be made visible. The broker should never see these values unless stealth mode Boolean input is set to disabled by the user.
If stealth mode input is disabled then EA does not need to send random figures of 150 to 320 pips but rather the user defined stop loss and take profit should be sent with entry order and made visible to broker. (default input for stealth mode = enabled)
c)EA System needs to support trailing stop. Trailing stop needs to be in two folds
i) The first is the broker hard stop loss EA will move the broker displayed stop loss to the trailing stop value when set.
Eg buy EUR/USD at 1.4220 trailing stop of 30 pips when price moves in favor of trade direction to 1.4250 then EA moves the broker stop loss to 5 pips above entry price so broker stop loss is now at 1.4225
This is to protect trade incase market moves too fast for EA to re-act.

ii) The second fold is EA trailing Stop (Soft Trailstop) this is the trailing stop to be used by EA to lock in profits it is NOT visible like stealth mode it is managed internally by the EA but works much the same as the hard trail stop above accept it is not visible to broker and managed by EA.

2)Smart Profit: Input value is boolean i.e. True/False. EA to exit half position when trailing stop target is reached. Example: buy 2 lot of EUR/USD at 1.4105 trailing stop 20 pip when price moves up to 1.4125 EA to exit half the position in this case 1 lot at 1.4125. The remaining position will continue to be monitored by EA with trailing stop. EA internal trailing stop is now at 1.4110 5 pips above entry price for a buy order. This means if the price does not go any higher and falls back it is protected with this trailing stop.

My Question for Stealth Mode, Is it even possible to hide SL/TP from broker?
because my personal perspective anythng that we send to the server can be seen by the broker. So if we hide TP/SL it will be considered never existed by the server, thus will never touched.
Anyone else have another thought on this Stealth thing?

My Question for Smart Profit, Is it possible to Close partial lot without using OrderCloseBy command? (is it beroker dependant?)

Thanx in advance for you answer.

1) Yes, Stealth mode is possible. My trades dont have a StopLoss or TakeProfit entered into the order - I just open and close with market orders. You simply close when pip_profits>=(Your desired TP) or pip_profits<=(Your desired SL)- Your client wants you to add a TP/SL of a randomly assigned value of 150 to 320 so just create a random number of 1-171 then add 149 to it. do for both TP and SL. You really dont need this though (newer EA's brag about this) - Easier just to not use a TP or SL at all. - He prob got the idea from this piece of software: http://www.broker-nightmare.com/ or MegaDroid since they brag about being stealth too. Ha! Get a honest broker! - Stealth mode cant protect you from freezes, slippage and requotes.

2) Yes you can close partial lots - Ex: 1.0 lot trade - You can close 0.5 of it and 0.5 will still be active.

Thanks guys for your answers
Now i know what it means by Stealth, because we manage the TP & SL on client side.
And just like what Fulltime247 said, Stealth mode cant protect you from freezes, slippage and requotes,
and it would be a disaster when the Terminal crashed and cause the EA "dead" w/o the user knowing it.

Oh, btw, i have another question, but it's about Script.
Script start() only called once isn't? so in order to wait for a signal from indicator we need to loop it and use the Sleep & RefreshRate functions.

I wonder is there a way to know on which order the script being dragged to?
For example there are several active orders, i want to close one of them by script by dragging the script onto the order or by dragging the order onto the script,
but i don't know how to get which order connected to the script, any one know how this can be done?

your don't attach scripts to orders, you attach them to charts. what each script does is all dependent on how its been programmed.

I can run a script that closes only the trades that has the same symbol as the chart that the script is attached to.

I can run a script that closes all trades regardless which chart I attach it to.

I can run a script that closes only EURUSD orders regardless which chart I attach it to.

I can run a script that closes all trades in profit.

I can run a script that closes all trades in loss.

I can go on and on....

hope this clears things up.

I see, thanks for the clarification Zen
I guess there is now way to close selected position using script.

Can you explain the functions

some1 wanted to have the trail, sl, tp hidden, thats what these functions do

honestly, iv been watching multiple accounts, variouse brokers, live accounts, 5+ years

iv never seen any indication of manipulation cause of my sl

i believe this whole stealth thing is for nothing, i dont believe in stop hunting

I agreed, i don't believed in stop hunting also

Why would brokers watches each of their customers trading individually, like they have nothing else to do.
It's not like we're special amongst other traders and deserve to be watched all the time

Stop Hunting DOES exist if you're with a scam broker. Your broker can see where every order is grouped and if he catches quite a few peoples StopLosses grouped around a certain level they CAN spike you and take you all out at once and put that cash in their pocket. Scammers can requote when price in your favor, freeze the feed, pad the spread, widen the spread, smooth the price feed to KILL your indicators (cough, IBFX, FXCM, cough..), etc... A dirty broker has all kinds of tricks to put your money in their pocket if they trade against you and dont put your orders into the real market. Thats why I only trade with ECN's.

i agree with you, about smoothing price, messing up indy reading, spread increase, re quotes, purging your data multiple times a day

i guess what i meant
i think hiding sl is a waste of time

iv watched various feeds, iv never seen a significant difference to prove that a broker spiked price that didn't exist on all the brokers

you have a good earning, what ea are you using for your trade?

if want to programme ea by myself, it must start writing start from zero or using software to write it? example this software: http://www.forexgenerator.com/
