Does US100 have good reversion properties?
You seem to take an overall direction for the day, and aggregate into one direction?
Currently I use the price difference between Darwinex and FTMO as indicator for the day direction the marketmakers (or big boys) want to see. It's funny, I don't even know whether there is a reason for the difference, but currently it works. I assume they have different providers with different price calculation models for CFDs.
For US100 it helps me together with the daily chart and yesterday's high/low/close to decide a direction at the beginning.
As you know, nothing is 100% sure with trading. And later in the US session there can be a clear turnaround.
For timing I look for reversal or developing price action and at the RSI on the 1 minute chart.
There are more wrong RSI signals than profitable ones if you are only watching the 30/70 levels and wait for the hit, for sure RSI is not a holy grail for newbies.
But experience with it helps.
I've also written an indicator for my MT4 terminal which shows me "my" trading zones. It's not perfect, but maybe I should offer it at the mql5 market anytime as it might be also interesting for other traders. I don't trade it, but I regard it.
Generally I try to get an impression out of all of it for an idea what will happen in the next 15 to 30 minutes or the next two hours before I place my first trades. That impression is more than indicators. Of course I'm not always right. The two trades you mentioned - I would have felt worse if I would have closed them with more than 1k losses. I missed the point to turn the positions early for short term trading, as I didn't have the intention for a reversal this time. And the basic idea for this US session was still intact - and stayed intact.
If a trade does not work for me, I cut my profit target to close it with some profit or close it manually with some pips on my side - it was just bad timing. Done. And I don't look back. Bad timing is bad timing. Happens again and again.
I don't use tight stop loss anymore as I lost more working that way than accepting a higher DD and the risk out of it and be more patient.
I love to use my trailing stop EA if I can set a break even stop loss to secure some pips profit. In the last weeks there was not much to do for this EA, US100 and DAX30 are more difficult for me than in some earlier weeks.
