The hedge range is configurable – anchor 200-300.
The increase factor xFactor is a risk parameter – 1.5-1.8 – the higher the value the higher the risk.

Risk can be further managed in the situation where conflicting positions are opened, (never good) by an assessment of the future trend and manually closing the offending one…

Some forex brokers will consider this scalping behaviour – a common problem with the best-looking robots and their forex trading methods, why do you think they’re onto it…

This expert advisor seeks to open buy and sell orders (independently). and with fixed take proft, stop loss.

Some forex brokers won’t go along with this one. And as always – this expert advisor is not recommended for online fx trades, the choice and risk is yours… – stick a forex practice account until good and ready is the best advice.

“what goes up must come down”

- and who’s to say this isn’t as valid a way of looking at it as any more complicated method of forex trading…

This EA tests a strong movement – x pips over y minutes time period, after which it will open a reverse position, with a set of stops to reinforce it. It’s also a nice bit of code to tinker with parameters:-
Limit : fluctuation value,
PeriodX : time period
All the positions are closed when Amount is reached.

And of course, you’ll never learn to live with the forex brokers without the management of risk

if getProfit > AccountBalance()/1000 => CloseAll
allows exposure to be proportionate to your available balance.

This isn’t an EA to use blindly in a live forex account – the risk of exposure can be great, as you’ll see in any backtesting. There’s also a lock down option to clear positions at a given total pip value… 40-50 pips advisable,

There’s no reason why this would work any better or worse on any timeframe or currency pair…

Moving Average Convergence / Divergence is a measure of the difference between slow (long-period) and fast (short-period) exponential moving averages – EMAs – of currency pair. Because of its basis on moving averages MACD is classified as being a lagging indicator.

The fun lies in the tweaking of the parameters – starting with the standard set – 12,26,9 which fast EMA = 12 -period, slow EMA = 26 -period and 9 = signal line period – this parameter set is commonly used in stocks, but then trading forex isn’t the same thing as trading stocks. There’s a lot of scope for testing here, and a lot of literature out there on the web on this subject.

One of the tried and tested tips here is to get a toolbox of indicators for forex trading that you can trust – nothing too large and unwieldy – the mistake is often to try to follow a vast number of indicators, rather than learn the behavior of a small number of forex indicators accurately. MACD.

Martingale is essentially a double or quits strategy – and applies to any either/or, win/losegame such as tossing a coin for heads or tails. If, every time you lose, you double your bet, at some point you’ll win and recoup all previous losses, or so the theory goes.

Of course, your position will start to increase rapidly, and in the real world it may well be that you blow the account before recouping, which is the serious down-side to the whole theory…

No forex account, practice or otherwise, has infinite resources – so the exponentially increasing size of the bet and position will eventually blow the account – think grains of rice on a chessboard, for how that’s going to work, if you do reckon on using a straight Martingale system.

In the default mode, always consider drawdown since there are no stops placed – this isn’t an EA to switch and leave running for a week.

There is a smoothing component – see the graph for an indication as to how the position Balance / Equity can be regained after a negative run.
