tlb, when you're scalping, forget about 4hr trendlines, they're meaningless when you're looking for 10 pips, you're going to bleed like a stuffed pig trading this way
I'll give you a highly profitable scalping method which will probably suite your style..FOR FREE!!
Start using Fibonacci, works great on IG advanced charts. Whenever EU moves by 30 pips or more then place a trade to retrace that movement back to the the fib 38% point (subtract spread from exit price though), if the price carries on past your entry then redraw the fib lines and still exit at 38% (your profit will reduce but you have a clear exit point)
You will make more pips scalping this way per day with far less trading...
I challenge you to find any movement on the EU on a m5 chart which has not retraced by 38%...does not matter where EU is trending, EU is highly liquid and never moves in a straight line...only use this for EU because it is so liquid and also avoid using it during major news events. Also works best when both US and Europe sessions are open 14:30 to 16:30...
Seriously, try it, give up on current method...please!!
