Predatory Algorithm blocking trade

View Count: 362

Hello,

I am noticing a predatory Algorithm targeting my account over the last few days, each time I place a trade on Sierra Chart, all symbols traded.

How can this targeted algorithm be removed or disabled from targeting my account?

Every single time I place a trade, the trend direction IMMEDIATELY reverses and aggressively pursues my SL (live and demo), no matter how far it has to STRETCH for it.Once my SL is conquered, it IMMEDIATELY flips and the trend continues in the original direction. EVERY. SINGLE. TIME. (Reversing positions has same outcome, live vs Demo =same...)

Please Help...

Thank you kindly

If I were you I would try out the simulated account until the problem is resolved.

I haven't ever experienced this problem using SC.

I appreciate your input. It also happens on the simulated account. Previously, I've noticed it in the currency pairs, so I stopped trading those.

Unfortunately, now it's happening with the Futures market, & Gold.

So I'm curious what solution Sierra Chart can assist with.

You are saying that the data moves in a specific direction when you enter a trade? So you believe there is some kind of predatory software causing this to occur?

We find it hard to believe that there is any kind of software doing this. It would have to be specific to Sierra Chart, and it would have to manipulate the data itself. Why would anyone build something this specific?

Have you looked at your chart data when this occurs and compare it to another source? Is the data actually different?

Yes, I do believe some predatory activity is occuring.

My computer is home today (I'm at work).

So I will start collecting screenshots from different sources to demonstrate what I'm observing.

Will follow up, thanks.

In a simulated account what happens when you enter a position ( long or short) but don't use a stop loss or a profit target?

Haven't tried that, but even when the SL is placed completely out of reach on demo, the immediate reversal still happens, and lasts for hours, (including overnight), or until the millisecond of when I exit the trade....at which time, it flips back to the original trend direction and speed. (The speed is MUCH faster when the SL hunt is occuring).

@ John Sc Support! Someone might build that cause it would be a money printer!
Can anyone tag Kenneth C. Griffin! Alex Gerko!!!! LinkedIn maybe?

@GARYtheG would you please share more details about this? Because the pattern I'm observing is odd, but very persistent and can't be accidental

@User852578, if you could so kindly give me your entry and stop losses, I will pay you. Sounds like you have a supreme edge.

Namaste! <3

Interesting problem to have.

@User852578, if you could so kindly give me your entry and stop losses, I will pay you. Sounds like you have a supreme edge.

Exactly .. assuming it's legal, if I had that problem, I would start a subscription based trade alert service ... money printer indeed. Why the heck would I bother trading anymore.
