Trigonometry and forex
the last part is getting the PTV for the true hypotenuse and using cos and sin rule (trigonometry) into time and price (note) note I.

I'm passing along a quick and easy little memory aid for Trigonometry that I picked up in Machining school decades ago. To this day I can instantly recall it and do all Trigonometry with it. The side Opposite of the included angle you are calculating. The Trig function calculates the angle between the 2 sides you use.
For good measure and convenience throw in:. The first thing that I do whenever I encounter a Trigonometry problem is to say the phrase to myself sounding it out like the latter phonetic 'translation' and then quickly jot the 3 abbreviated equations down and I'm off and running. Doug, do us all a favour and focus on programming your strategies and helping us all do the same. For Forex, O H A B maybe some is time, and some is price, theres are not in same unit, so the difficult is not always Trigonometry, but what is the dimension unit.
As you say, math is very pertinent and hardly irrelevant in ForEx figuring. All knowledge begins with 'I do not know' and that is certainly applicable to me here. It is quite obvious to me that there are lots of others here that know a LOT more about higher math that is very relevant and applicable to ForEx functions and programming than I do and I am learning as I go like everyone else here.
I did trig for years without knowing this handy little memory aid. I haven't done much trig for quite some time, but I can still do it because of this little pointer. I don't have a great 'wrote' memory and wouldn't have it readily accessible at any time now without this tip. It is quite likely that there are others here either now or in the future that will be happy to learn it as well. I know I was. As for the different fonts, I do tend to use large fonts due to visual impairments which are currently compounded by a very lousy and small monitor and not because I am an egomaniac or a PrimaDona starved for attention and thus always have to have the spot light always focused only on me.
I wish it was all bigger, it would make it significantly more accessible to me. Some of the variety of fonts and sizes are conscious formatting to make the priorities quick and easy to skim over and pick out by those that are already knowledgeable in this area. They are there for the same reason that there are thousands of different fonts when only one is really needed to communicate something: to make distinctions. Frankly, what difference does it make? If the formatting options aren't supposed to be used, what are they there for?
This tip is relevant for those that don't know it but will utilize it in ForEx programming. FYI: no one ever responded to share the information with me. The thread topic that is posted for this tip is short and succinct and to the point. I have found entries posted between other's here about Obama. This hardly falls into that category of irrelevance to ForEx programming. All that being said, point taken and duly noted. Rather than increasing your font when constructing a message, have you tried doing something a bit more "global" like using the accessiblity features of the OS or increasing the size of the font in your browser's rendering config?
That way you'll be able to see all of our posts easily. After all, you already know what your own posts contain. It never really crosses my mind whether or not other folk on this site are making money from the forex market. My concern here is really with MQL programming and that is all. I am making money out of the forex market - I have part ownership in a research company and my EAs are used to trade significant assets under management.
I would blooming well need to be making money from it :- as my main career as a commercial chopper pilot is quiet this year, due to the global financial situation. As the Azies would say: Gud on ya! I'm glad to hear that there are at least some people on here that are actually successful ForEx traders.

Though they are closely tied, you should understand the difference between the two, and know how to calculate each. So, what is leverage in trading? Leverage gives a trader the ability to control a larger position by using a small portion of their own funds and borrowing the rest from their broker.
What is Margin? Margin is the good faith deposit required by your broker to allow you to open a position. Using these funds coupled with other client funds, the broker can then place trades with their liquidity providers and interbank partners. Leverage can be calculated using the forex trading math formula below:.
So, the effective leverage in this example would be expressed as Brokers in the United States offer upto leverage for forex trading, while Forex brokers in other jurisdictions can offer leverage upto in some cases. But is very important to keep in mind that leverage should be used responsibly as it acts to not only amplify returns, but also magnifies losses. Position Sizing is one of the most important and frequent calculations that you will need to make as a forex trader.
In fact, before any trade that you consider entering into, you should calculate the proper position size based on your pre-defined position sizing model. One of the simplest and most effective position sizing models is a fixed fractional model. Once you have determined how much you plan to risk on a per trade basis, then you would start by determining where the most logical stop should be placed on a particular trade.
One you have located a level where you plan on placing your stop loss , measure the distance in pips between this level and your intended entry. Then jot that number down and keep it handy. Now the next step is to determine the value of each pip. We have discussed how to calculate the value of a pip in the previous section. Once you have this value, you are ready to calculate your position size. Here is the trading math behind Position Sizing:.
Trade Expectancy is one of the most important metrics that a trader should be aware of. But what does it mean? In a nutshell, trade expectancy is the average profit or loss that can be expected on each trade based on your average Win Percentage, Avg Win Size and Avg Loss Size. Here is the mathematical formula for Trade Expectancy:. Typically trend following systems tend to have low win rates, but relatively large average wins compared to average losses.
This time we will look at a Mean Reversion strategy. Mean reversion strategies tend to have higher win rates, and the average wins and losses are somewhat similar. Many traders make the mistake of only relying on win rates when evaluating trading systems.
How many times have you entered positions in multiple currency pairs and noticed that their price movements were related? To understand this better, you have to know what currency correlation is and how it can impact the overall risk in your portfolio.
Currency correlation is a statistical measure of how different currency pairs move in relationship to each other. Currency correlations can be positive, meaning that two currency pairs move in the same direction. Currency correlations can be negative, meaning that two currency pair move in opposite directions.
And finally, currency correlation can be neutral, meaning there is no discernible price relationship between the two currency pairs. The forex mathematics behind currency correlation can be quite complicated, so we will not get into that in this lesson. But fortunately for us, we do not need to know the trade math because there are many currency correlation tools available in the market that makes it easy for use to do our correlation analysis.
Most currency correlation tools are presented in a table format. Remember that a positive value means that the pairs move in the same direction, while a negative value means they have an inverse relationship. As traders, we know that we will have losing trades and that they are a natural part of trading. Essentially, maximum drawdown is the maximum loss in equity that our portfolio incurs over a period of time.
It is the largest drop from a previous equity peak to the lowest point after the peak. We can calculate the maximum drawdown after a new peak has been put in place on the equity curve. Here is the math formula for calculating Maximum Drawdown:. What is your Maximum Drawdown in this scenario? So, the Max Drawdown in this case is Drawdowns can be very dangerous to the financial health of a trader because, as your drawdown increases the return needed to recover becomes larger and larger.
Let take a look at the table below:. As you can see, the larger the max drawdown or capital loss the higher the percentage gain is needed to recover the losses. This is one reason why it is critical for traders to trade small so that they can try to keep drawdowns to a tolerable level.
I would venture to guess that most retail traders have either never heard of Risk of Ruin or if they have they do not really understand its power when it comes to risk analysis in the markets. Risk of Ruin is the likelihood or probability that a trader will lose a predetermined amount of trading capital wherein they will not be able to continue trading. It could be any percentage that the trader determines will be the point at which they will stop trading a system.
The Risk of Ruin is calculated as follows:. There are several simulators available for free that you can use to calculate the risk of ruin.
