Why do I use 'open price only' instead of ticks when I backtest my EAs is a common question.

The answer is very easy, the kind of prices necessary for backtest with reliability depends directly of the kind of system, how is programmed and executed the system.

I mean that if you follow some guidelines when you programm the EA, the 'open prices only' can be more than enough for proceed with the backtest. What happens in this kind of systems, is that backtest with 'open prices' or with 'ticks' will produce 99,9% the same results.

Therefore, don't make sense spend more time and resources backtesting in 'ticks'.

In the case of my EAs, they works this way, the result is the same using open prices or ticks.

As general idea, this can happens if you program a system which only acts at the beginning of the bar (which is the case of my EAs). In this case, what happens inside a bar doesn't matter because you don't take actions depending on this.

But the final reason why I use this kind of programming in SFE EAs, is not for not spend more time backtesting in 'ticks'. Is because I think that a system than needs the tick information to work is too risky, because is a system which works very fast when volatility can be still out of contral, and in very narrow ranges, and in this case, the backtest is not reliable (even using ticks) because the mt4 backtest don't represents well the punctual spread and slippage issues, and with systems which focus on ticks, this issues have a big influence.

In brief, in case of SFE EAs, backtesting on 'open prices' or 'ticks' gives the same result at 99,9%. We don't have to consider 'open prices' a 'low modeling quality' in this behaviou, and remember that the information of the bar in 'open prices' is correct, I mean the high, low, open, close and volume.

« on: June 16, 2019, 09:53:38 PM »
KISS is an acronym for "Keep it simple, stupid" as a design principle that most systems work best if they are kept simple rather than made complicated.

This expert is the result of simplifying at maximum level the algorithms of the others SFE 'price action' based experts.

The use of the expert is very simple, and needs very low computer resources.

SmartForexExpert EAs / SFE Night Scalper EA
« on: June 10, 2019, 10:47:55 PM »
This system takes advantage of the stagnation of the market at the final of the New York session and the first hours after that close. It detects small deviations and enters in the contrary direction trying to close the operation in the level before that deviation happens. If the operation does not close with profit during the stagnation hours, the EA tries to exit in a favourable condition in the next hours, before the European session opens again.

SmartForexExpert EAs / SFE Price Action EA
« on: June 10, 2019, 10:47:30 PM »
SFE Price Action is an Expert Advisor with a great diversification of operations and different systems working in  several pairs and timeframes at the same time. This increases the chances of sustained growth and reduces exposure to a single pair or individual operations. The risk is very controlled.

Based on own price action rules, no hedge, martingale, grid or any other type of dangerous practices are used, such as not closing failed operations.

You do not need any knowledge, the configuration is very easy and you do not need configuration or optimization work. It is not necessary to be alerted about whether the EA should be enabled or not. Due to its high diversification and low risk, it is safe to leave it always connected.

Counting on a 10-year backtest period and more than 4.0 years of live action since mid-2014, it shows the EA's great adaptability to any type of structural behavior in the market. The robot bases its advantage on intraday volatility, which often occurs independently of market bias.

Other Brokers / With or without commission accounts?
« on: June 10, 2019, 10:32:59 PM »
Avoid accounts without commission

Offer trades without apply any commission is a way to attract newbies to this kind of account. Read the recommended brokers section to see which kind of accounts we recommend, but we want to post here a consideration about commission / no commission accounts when the broker offers both options.

Choose always the account with commission. The account without commission has a simple trick very easy to understand, the commission is putted hiden using a wider spread.

This means at the first moment, that your entry price is worst. Until here you can think that altought the entry price is worst, you haven't paid commission, and therefore is the same. But in forward, during the life of the open order, the spread is still higher, and what this mean? mean touch the Take Profit less times, and mean touch the Stop Loss more times.

Don't seems much but the effect is more great than seems. And is specially critical in systems based on a large number of operations with a narrow value of profit / trade.
