thanks for reply.
enter at $5
Stoploss at $4.50
Trailing Stoploss at 4.80
When I entered at $5 then market do not go up. Market go down from $5 to $4.6. Then what will happen in this case?
These are 2 different cases, if you change a Trailing stop loss to $4.80, your first SL is modified. So now TSL becomes new SL. Now any time markets go below $4.81 your are out of trade with a loss of 20c a share.
Consider this
If your original SL is still $4.50 and you don't modify this SL (means you dont add a TSL) and markets go down directly from $5 and below, your trading plan is prepared to risk .50c a share,
so in this case at $4.60 nothing happens, unless markets go down to $4.50, at $4.50 you will book a loss of 50c a share, this is called Market Risk.
Every trade you do involves certain kind of risk. You decide to limit that risk by putting a STOP LOSS, In our case we want the risk to be limited to .50c a share.
Please also note, if you are looking at your trading window, there is no extra option to use TSL, you need to modify your SL order to make it a TSL.
Also never add a new SL, always modify the current Buy/Sell LIMIT Order ( SL) to make it a TSL with new value... for example you go to Sell Order Of SL and then you click modify ( change the value of SL to make it a new SL) or in other words TSL.
I hope this helps
