Why Not To Use Stop Loss Order

I’m busy investrader trader. I work full time so it is not easy for me to trade throughout the day. Thus, from time to time (read: sporadically), when I’m going to the meeting with an open order, I need to minimize damage to my portfolio in case something was happening to the stock while I was not looking at its chart. During those times I use stop-loss orders. Stop-loss orders are dangerous and I want to share with you something about them.

A stop order (also stop loss order) is an order to buy (or sell) a security once the price of the security has climbed above (or dropped below) a specified stop price. (Note that both bid and ask prices can trigger a stop order.) When the specified stop price is reached, the stop order is entered as a market order (no limit). This means the trade will definitely be executed, but not necessarily at or near the stop price, particularly when the order is placed into a fast-moving market, or if there is insufficient liquidity available relative to the size of the order.

I filled an order for 400 PFE at $17.90 (its support). I set a stop-loss at $17.78– I like to take tiny losses. While away, look what happened:

For a fraction of a second, the price fell to $17.75! Coincidence? This is what happens when others set stop losses and the movement is bearish– they are being taken out within fraction of a second. More importantly however, stop losses can be seen by market makers and they sure know how to make your life miserable.

Regardless, my stop loss order was not taken out and I’m still in this trade.

Best of all, just see what happened right after:

First Forward Testing of the system a Success [MOV]

General / Comments Off on First Forward Testing of the system a Success [MOV]

Forward testing is when you use a strategy and instead of back-testing it with previous data you actually test it going forward and preferably with real money.
For my new system MOV became that victim stock to be tested.

I first got a buy signal on  April 17 2009 (Bought on the 20th at market open), i got in at 7.67.
I got a sell signal on May 5th 2009  and I sold at  8.81 with a market order.

I got about 14% profit on a 19 day long trade.
I don’t have a chart to post with this one but just wanted to say this first forward testing trade worked well.

Here’s to more good trades.
