In this post I'll try to explain some of the problems with relying on absolute candles and closes, relative to time periods.
I'll explain a real situation, but it's exaggerated for demonstration purposes only :-)
You've been watching a stock for a while on the hourly chart. It's been bouncing off resistance the last couple of days but in an ascending triangle. So you decide if it breaks resistance and closes above the line then you'll go long.
Unknown to you though, on the other side of the world there's a bank clerk sitting with an order on his desk to sell a million shares in that stock. It's a big enough order to spook the market and make the price drop 20 pips in a couple of seconds.
The time is coming up to 11.00 and you're waiting for the 10.00 candle to close, so you can make your decision to go long.
At the same time, the clerk is thinking to himself, "will I put this order on now or go for a quick pee first ?". He opts to go for a quick pee and holds the order for a minute.
So the candle closes at 10:59:59 and you go long.
Just then, the clerks order hits the book and the price drops 20 pips in a couple of seconds.
No problem though, maybe it was just a bad trade and you'll get stopped out. Maybe it will bounce and go back up, doesn't really matter, just normal business. In this case, it was a bad trade and you get stopped out as the price falls away over the next few hours.
But what would have happened if the clerk had put his order on just before going for a pee instead of after ? In that case the candle would have finished like this, a very bearish pinbar.
Would you be long in the market on that signal ? Hell no ! All the bears are probably waiting for "pinbar at resistance" signals to go short, so the price is going to drop.
Hopefully you can see why the close of a candle at a specific point in time can be absolutely meaningless. It can go from a strong buy to a strong sell in a matter of seconds. In my example, a couple of seconds either side of the hour could make a big difference. The end of the 'hour' is completely arbitrary.
But people absolutely insist on a 'complete' candle to make decisions. Some will or won't take a trade purely based on where a candle closes in that one tiny second of an hour long period.
Retail traders need to start thinking a bit more flexibly about what they're looking at. I don't necessarily think it's a good way to trade, but the motto is 'always wait for confirmation' and let the price tell you what's really happening.
If you rely on the shape of complete candles then very often they're going to be wrong and you're going to enter a bad trade.
Even if they are correct, you've already missed your chance and you're entering the trade too late (I'll discuss this a lot more in a future post as it really separates the people that make money trading from those that don't).
In parting though, there's one caveat to relying 100% on candles. If you're trading a 100% mechanical system, then you need to define a single point in time that says 'buy', 'sell' or 'stay out'. But that's on a non-discretionary system that you've backtested to hell and know the statistics of. The candle close time is just the 'yes/no' decision point, only because you need a single point somewhere.
But instead of exactly the end of each hour, you could make the decision point every 37 minutes and 42 seconds after the hour. There's just no reason at all why it needs to be exactly on 00:00 every hour.
In the next post I'll explain about blending candles and why all candle patterns are the same pattern on different time periods.
