I'm going to echo some of futurespec's sentiments. After an initial bumpy start with the forced installation, and until I changed my shortcut to use the /portable switch to get my old MT4 file structure back, and as a developer who generally isn't ...

MT4 New build 600 is released

By the way, Oanda just pushed build 600 on this machine. I tried to kill the process, but it was too fast. Good thing I took Hanover's advice and made a backup this past weekend. Word to the wise! Thanks David!

MT4 New build 600 is released

Hi G, It sounds like you're just conceiving of how to trade the indicator as a system. I think of what size to trade as a sort of equation that can be solved, given the individual's goals. If you are trying to solve the "double your account in 1 ...

Fractals, ZZ & the Pissing Dog

G, I was wondering how long it would take you to get to the implementation stage! I would trade this strategy the way it was designed in its indicator form - as a pure reversal system. This obviates risk/reward. Simply determine how much you want to ...

Fractals, ZZ & the Pissing Dog

I'm sure it has been asked before but I couldn't find the answer. What is the procedure when the fractal pattern is not found in SET2? Move on to the next step? Reduce fractal length and try again for a match? Other procedure? Adding the fractal ...

Fractals, ZZ & the Pissing Dog

You are sequencing strings of length 4-13, but are not sequencing multiple length 4 strings, multiple length 5s, etc. Instead of 6 (below) think of 13 as the total string length you are trying to break up into pieces.

Fractals, ZZ & the Pissing Dog

The efficient market hypothesis seems to me an attempt by economists to justify their lack of ability in creating profitable trading systems. The false premise at the core of EMH is that because markets are efficient, nobody can make any money ...

why have you accepted the price-predictability assumption?

The markets are efficient in the sense that there are no free arbitrage opportunities sitting around for a retail hero to take advantage of. The market distributions also have fat tails, indicating the presence of trends, an inefficiency. So ...

why have you accepted the price-predictability assumption?

I suppose the simulation I was doing could be termed monte carlo because it uses randomization so yes though I was not thinking about any sort of strict or even that rigorous of a testing procedure. More like whipping out Python scripts to test ...

One Way to Develop a Winning System

On the open source front, I've been eyeing this one: TradePlatform TradePlatform.NET is addition to MetaTrader 4 client terminal which extends trading experience, MQL language and provides .NET world communication bridge. And I also ran into this: ...

Calling MT4 commands externally (e.g. from C++)

Yes I think this applies in the case of any discretionary trader / system. If there is really a system that is consistently followed (mechanically), and the system is built on a sound foundation, offering a real advantage, then the probability stats ...

How many trades until a system is proven, not just lucky?

Did you see the Matlab code working out some of the chapter exercises from the book? url See Publications / Books for the publisher's website. I was thinking of converting some of the code to R where it is easier for me to use in a trading ...

Quantitative and Algorithmic Trading

Thanks for your comments. The quote was from 2007 but I still favor systems that use SAR, vs. using a discrete entry and exit in systems I create. I guess the main reason is that SAR systems seem to be easier to create, or tend to be more profitable ...

Apologies for the late reply. I don't consider myself to be an expert on any of these topics. However, I have found that simulation is one of the better ways to discover what works and what doesn't. In particular, running different MM simulations ...

One Way to Develop a Winning System

Well stated, nubcake. And I would add that this ratio: (daily range) / spread is one of the best methods I know for choosing which pair to trade, or for making an objective comparison between pairs on the basis of general tradability.

Quantitative and Algorithmic Trading

Gambler's Ruin: a gambler with finite wealth, playing a fair game (that is, each bet has expected value zero to both sides) will eventually go broke against an opponent with infinite wealth.

The one reason that trumps all other reasons why traders lose

I hadn't thought of using the EMA of trade size but the idea sounds extremely interesting. If you take a look at the paper in the 2nd link: "Betting with the Kelly Criterion", there is a derivation of the continuous formula in section 3 (starting on ...

One Way to Develop a Winning System

As an update to the topic of Drag-Free Position Sizing I've recently been doing some MM simulations using percent of equity sizing. The Kelly Criterion is a special case of a percent of equity sizing method that also happens to be median log wealth ...
