A couple of things you can do is when you're chaining in, input j.a/j.b early to slow down/stop the momentum. This causes you to stop at a certain distance and block before your opponent (depending on the timing of your input) and allows to you to bait DP/anti-air/5a. You can also do 5D~D/B/C then midway through do another 5D~D/B/C. Try not to use 5D~C alot to approach since it can be easily mash out of. 5D delay D is also good too when you're in the air or 4D~D quickly to approach real fast from quite a distance catching him off guard.
At close range, if your opponent like to 5A your 5D approaches, you can try doing 5D and just before it touches your opponent, hit A to retract your chain. This causes his 5A to whiff and if your spacing is right, this allows you punish him e.g. 3C into Houtenjin stuff.
One last thing, just be mindful of your chain stocks.
